Please recap S1 before watching S2. These are all from my point of view. I hope you can understand the story better after reading. I don't want to write too long but the injustice for rating is too much. I don't mean the reasonable ones.

SO has always been the ML and HY is 2nd lead. SO is more interesting character while HY is a nice/good character through out the show. Just because JJ chose HY didn't make him 1st ML. HY might really be ML in Webtoon but we are talking about drama here. I am not interested in Webtoon too.

This is for all of them in general:

They were high school so they must be 17/18 years old which means we as a viewers has to accept that they were immature. Not just because of their age but by the way they act. I think human maturity are affected by our age, situations, events, tastes and feelings. (Maybe there are more but I will stop here cos I don't want to think anymore. xD)

Then, 4 or over 4 years later, they met on crosswalk. SO got gf (YJ) and JJ & HY were single. So, they were 22/23 years old now. They seem a bit mature in appearance.


Sun Oh is handsome, has very high background, actor, model and no love from his family. He has control freak/possessive parents. Maybe that's where he get his possessiveness, bold/daring and inconsiderate/too cold personalities. His parents were too cold to him and didn't bother about his feeling but their own success/love/happiness.

But he got his best friend Hye Young who stand on his side until he found out that his best friend has a crash on Jo Jo. Maybe he didn't want to lose someone dear to him so he got interested in a girl who was his bf's crash. But then, he went ahead and kissed JJ with his bulldozer/daring personality. (Yo, I am not saying that this is his fault alone but also JJ. But wait for JJ turn. It will come later)

Then, I wondered why he is so daring? It must be because he got everything like money, fame, background and appearance at high school. Isn't he taking things a bit too easily? He is like, "I will be good to my bf and the girl I love." But he forgot to consider their situations. He didn't think what would jealous people or people around them would see them differently and treat them differently in a bad way cos they were poor. (Will you let someone do as they like cos they are immature? No. Not for me.) That's why HY didn't ride the car with him. He already took a lead with a kiss and love alarm with JJ. But then he said to HY, let's fight fairly. What? He was already way ahead, do you think anyone could beat him at this stage? That's why HY uninstalled love alarm not to interfere with them. He totally backed off for his bf. Then, SO & JJ enjoyed their moments until they got into accident. His father told him to do as he will or he is going to send him abroad. So, he continued his life as actor/model and failed all audition badly? He dated YJ cos of his parents?  (I might be wrong)

In short he did as he liked without consideration for others just like how his parents treated him. But he at least treated HY, JJ & YJ better than how his parents treated him. He just didn't think about the consequences of how it could affect them by others.

Then, 4 years later SO met her again on crosswalk but just passed her like he didn't notice. That's okay cos he seem like he was trying to get over with JJ. Then, he interfered with JJ & HY so that HY won't get hurt. He also wanted to know why JJ broke up with him? Why was she giving a chance to HY but not him? Then, he found out that JJ had loved him and she didn't know she will ever love anyone as much him again. He then said that he will believe if she rang HY love alarm. They met again at Love Alarm 2.0 launched day and time skip for whatever reason. (I was like, wth just happened. JJ & HY became a couple in S2E1 and he just continued his life.)

Then, JJ & SO met again at school. Then, at Love alarm badge club SO found out that JJ installed a shield. That's why she couldn't ring his love alarm. But JJ told clearly that she wanted to remove the shield now cos of HY but SO couldn't believe it.  So, he thought, JJ was lying this whole time and not to get caught by him, she dated HY to protect her feeling from him. Then, he went to JJ college and ask her out publicly just like when they were in high school. Did he think she will be impress? Shouldn't he wait for her to break up first before he did anything with her? e.g., a kiss at alleyway & asking publicly in college. The first time, she was someone else gf and his bro's crush. Did he forget that she is his bro's gf now? Then, he pecked on her lips again. Maybe he did it to let her remember their past again and to like him again. Then, SO found out that JJ came to his house from his mum later. Then, he followed her to ask it was his fault? She answered that if she stopped, he could continue smiling. So, he thought she did it to make him smile without her. Then, while fighting HY, SO thought HY was making thing hard for her cos HY didn't know that JJ was doing all this to hide her feeling from SO when the video went viral. That's why he was able to get angry and hit his bro cos he thought he was right. So, SO felt restless to make her love him again. Then, he met JJ and found out that it was her choice and not love alarm when she came back from HY house. He felt crushed by JJ words at that moment. (I felt so bad for him at that time. But he shouldn't lie himself anymore. I was screaming inside, "please, move on already SO") After that, JJ rang HY's love alarm in front of him and SO accepted from that time to start moving on. YJ had to travel cos of that viral video too. Celebrity getting rejected by someone that no one knows was quite shameful to YJ. He should have think those through before he causes this big problem. (Aw. Poor YJ). Then, HY came to met SO cos he also found out about a shield and a spear. JJ had already confessed to SO that who did he think she likes now. SO should have just helped them by telling HY that she truly like him now instead of staying quite and answering, "I don't know either but I do know that it's her own volition." Maybe he was still holding on last hope and didn't want to believe it. (Well, what can I say, he love her so much. I can only understand for him as a viewer.) After finding out that TRW's artist was JJ, he finally understood that he ain't the only one who had been having a hard time cos of a shield. Then, he met with JJ and told her that she didn't have to feel sorry for liking him and liking someone else now. He understood by now that she did all those choice for her own sake (To free from exhausting life back in high school and change of heart after 4 years) and not his fault. So, he let go of her and move on with YJ. Maybe he felt bad for YJ's 4 years long efforts and giving trouble to her. (I think he did care for her and more considerate to her than JJ although he forgot to think through of the consequences most of the time or each time. But he always went back to her. XD. I feel that YJ might be a bit too good for him but that's YJ's choice.) Anyway, writer has the most authority to make choice cos it is hers.


Hye Young is a nice guy who was coward to hit on JJ at high school. He lived at someone else house, he is poor and his crush (JJ) has a bf. Maybe he is not hitting on her cos he thought about circumstances and a time to date. Then, his bf, SO came back and went to same high school with him even though his social status is on another level. (Maybe there is only one school in this drama. XD) (Actually, cos SO wanted to go same school with HY.) Then, his bf kept on asking him if he like her or not. Then, he was not going to think about any situations and go with his heart but couldn't met JJ that day. Then, his bf kissed HY's crush and JJ rang her love alarm. As SO asked HY that he wanted to help JJ, he said stay by her side just like him. Then, HY decided to uninstalled love alarm for JJ & SO. Then, SO & JJ got into an accident and HY tried to let JJ connect with SO. Then, they met again at crosswalk. As SO & JJ had break up and HY's mum said to live freely, he mustered up courage and start hitting on JJ. She kept on rejecting him but he said that she didn't know what being alone means cos she had felt alone for so long that she didn't realize she felt that way. And he said that she didn't need to like him back and she could dump him too but let him ring her love alarm and keep on liking her. She accepted him at the schoolyard cos of HY touching words which warm her cold heart. Then, time skip for JJ, HY & SO meeting at Love Alarm 2.0.

They were already couple in S2. Then, HY kept standing by JJ side whenever she had a hard time and waiting for her without pressuring. He shared his problem with JJ and apologize her for lying. Then, he found out that SO publicly go to JJ college and ask her out. Then, he got mad at SO for doing that without consideration for JJ so he punched him once. After that he was so happy cos JJ rang his love alarm. But found out that she used the spear to ring her love alarm. So, he went to found out that SO knew about that or not. SO said that he didn’t know about it either and she did it on her own volition. Then, he got upset for pitying him and not sincere. JJ had told him to get angry, mad and to argue with her if she did anything bad so he did it this time. (LOL. This guy became a victim of love alarm app too. He should have thought through why JJ used the spear. Well, HY got too caught up in emotions & he had never kissed her, so that's what happened, I guess. Yup, writer did it again. Another Inconsistency in a character.) Then, he found out that she was sincere when she used the spear from Duk Gu. So, he went back to her side and listened to her side of the story and be together again.


Jo Jo had a tragic past and she had a fear that anyone would find out about her past. So, she lied and live her high school life. Then one day, popular, charming and handsome, SO started on hitting her. She fell for him and kissed him cos she was having a hard time with her inconsiderate bf, cousin and aunt. She was still paying for her grandma hospital fee too. She didn't think this through when she got bf and fell for her lust. Well, maybe she might have been very depressed. She got terrible friends who kept asking thing she didn't want to answer and had to lie. It was her fault for not being able to confront her feeling that she was a child who had no parents and worse they tried to suicide and she was the only one who survived. The next day, her terrible best friend shared the photo of JJ & SO kissing. She was trying to break up with her bf but SO came in and asked for her hand. So, she thought he shared the photo cos he couldn't wait her. Then, she pulled him away and asked if he did it? He answered that he didn't and that's not important cos they did kiss. Then, she found out that they both like each other by love alarm app so she forgave him. Later, she found out that HY, her boyfriend's bf ring her love alarm too so she felt awkward when she met SO with HY. Then, SO & JJ enjoyed happy time until the accident. Even before the accident, she needed to work, study and take care of her grandma every week. She still got debt to pay. She thought SO was rich and famous but she didn't think that he would be that big when she went to his house. His father called SO that he was useless and he would send him abroad if he kept acting that way. So, she thought SO's life was going to ruin if she kept staying by his side and everyone who were with her got bad luck so she decided to install the shield and broke up with him. He was too heavy/exhausting for her to continue her life too. She thought he could be happy and successful if SO forgot about her and continue his life. Then, 4 years later, JJ met SO & HY on the crosswalk found out that SO still rang her love alarm. But he got a gf this time. Then, HY came to JJ and hit on her openly and told her that he would only be doing this until he went to internship. So, JJ was like okay, he was not going to pester for long. Then, when she was having hard time with Gul Mi, HY came to stand by her and told her that she didn't know what being alone means cos she had felt alone for so long that she didn't realize she felt that way. Then, they went to the bridge and when HY shouted her name and wanted to make her happy, her shielded heart was starting to crack a bit. She also learned that night that he uninstalled love alarm when she was in relationship with SO. The next day, JJ went to meet HY and told him that the break up of her & SO was her fault and she didn't plan on loving anyone. But HY's words, touch her heart and she wanted to give him a chance so she let him ring her love alarm. Then, SO met with JJ and she answered that she might not love anyone as much as she had loved him but she felt sorry to try with SO. Then, they met at Love Alarm 2.0 launched date and boom, time skipped.

 JJ & HY were couple now in S2. JJ was starting to feel something when she saw HY now. Maybe, because he was always stand by her side whenever she had a hard time. (The drama didn't show that much but it kind of give a bit of that intention.) HY was there for her when a crazy fan chased her and when she found out that Duk Gu committed suicide. When she was at HY's apartment, he was warm to her and kept distance from her to make her feel comfortable. HY shared his wound with her and she liked the fact that he was able to face his emotional wound or problem head on. She was trying hard to confront her feeling with SO at that time. When she was on viral video, all she could think was HY and he didn't get angry at her. HY kept reassuring her that she didn't have to feel pressure and wanted to build thing up slowly. She felt his sincerity and love so she wanted to rang his love alarm in return. Then, on her way back to her house, she met SO and she was able to tell that she liked HY more now and not SO anymore. After seeing photos, she was able to see clearer now that she did love HY. So, she called him and rang him love alarm on the bridge. (I think she might have been making sure of her feeling this time unlike with SO which happened too fast. What if she break up again if things get too hard for her again.) Very next day, HY found out about the shield and spear and she didn't know how to explain anymore cos she did used them for her own sake. Then, she felt she was at the bottom of the ocean cos whatever she did, things always bad in a bad way that seem like bad luck was with her. But she didn't want to lose someone dear to her this time and she knew that HY might forgave her if she was sincere. It was her last hope too. So, she mustered up her courage and confront her feeling with SO. Then, she went to marathon to find herself, the courage to survive again. There she found out that it wasn't because she hated anyone (SO), it was just too heavy for her to carry/move on. So, it was no her fault or SO's fault or anyone fault. Then, she met HY at the end of marathon and told him all the things honestly. Then, JJ & HY lived honestly together.


2 years ago, when I first watched Love Alarm Season 1. I was totally rooting SO & JJ cos he was too bold & brave. I hated 2nd lead HY for being a coward and not hitting on JJ earlier. That's why he was 2nd lead for a reason.

But then, I recapped season 1 to watch season 2. My viewed has changed now cos I was able to see each character better. I know why SO was too bold and why HY was coward? Why JJ broke up? Why JJ opened up to HY? HY became brave after 4 years later and said some touching words to JJ. I think where HY rode bicycle around JJ in the schoolyard (S1E8) is beautiful and JJ quoted, "1 is bigger than any number in the world". Then, I was not sure who to root for anymore when the show left with cliff-hanger.

Those were before I have watched S2.

In S2E1, I was shocked why the writer didn't continue where cliff-hanger was left. But JJ didn't meet up with Brian Cheon cos she didn't want SO & HY to know that she installed the shield. But I want to see that climax moment badly. Why end with that cliff-hanger if they ain't going to show it. I am so mad about that.

Why did JJ choose HY?

JJ & HY were couple now. So, I was like, "Okay, let's see how SO will get JJ back cos he is the ML." But SO was telling JJ that she should like him cos she used the shield but she clearly said that she wanted to remove the shield now cos of HY. What worse is that SO went to college and ask her publicly when he knew that his bf is dating her officially now. Because of the viral video, it hurt JJ & YJ. Then, SO thought HY was making thing hard for JJ cos HY didn't know that she used the shield to hide her feeling when SO & HY were arguing. Then, he still wouldn't help his bf that JJ like HY more than him now when his bf got confused/misunderstood about why she installed the spear. I was able to accept JJ choice cos SO was too selfish and inconsiderate to JJ & YJ. I think JJ chose HY cos he would stand by her side whenever she had a hard time and he was opened about his wound to her. Maybe, she wanted to be brave like him and confront her feeling like him so he was kind of like an inspiration to her.

After watching both seasons and while writing this, I down rated S1 from 9 to 8 cos I am able to understand the story better now although there were plot holes.


Sorry for long review and Thanks for reading my opinion.

The link below is for people who think S1 is amazing and S2 is a trash. They were just above average for me.

By @BeulahGlory 

When we are not mature, we wouldn't be making right decisions. But that decision which we made when we are young was the most right ones to protect oneself with a shield (in order not to get hurt) at the same time. Its okay to let go when it is heavy. That's what FL says here. Good Life quote. 

I think this is pretty good quote. :)

I don't want to keep adding new idea to the main so I will just add it on new one.

JJ used spear cos she didn't want to leave the ringing world. She wanted to live in it and ring like everybody else now.

I totally agree with you! In S1, SO forced himself on JJ, constantly pressuring her and saying "you like me" "you like me" - basically manipulating her into believing that eventually herself. And SO succeeds with this manipulation, bc JJ's boyfriend, bestfriend, aunt, or cousin won't give her the comfort and support she needs. JJ is pretty much a broken and vulnerable person in desperate need of someone's comfort, so when SO forces himself onto her she's too weak and vulnerable to see his manipulation and can only see that she can get some comfort with him, so she subconsciously give in to his manipulation.

I also think SO only went after JJ in S1 Ep1 out of pure spite, bc he saw how Hye-yeong didn't take his call outside the bbq place and realised how he's not the most important person in Hye-yeong's life anymore. Sun-oh keep holding on to their childhood promise - basically expecting Hye-yeong to dedicate his entire life to him, not allowing him to have a life and love on his own. So to keep Hye-yeong to himself, he basically takes away Hye-yeong's "distraction". Like how self-absorbed can Sun-oh be?

Where on the other hand, HY didn't act on his feelings in S1 because he respected that JJ  had a boyfriend so he patiently waited. Opposite SO, who had no regard to that JJ had a boyfriend or that his bestfriend has the biggest crush on this girl, and forced himself on her anyway. And when Sun-oh dated Jojo, Hye-yeong respectfully stepped back and didn't interfere, uninstalled the Love Alarm app (so he wouldn't ring Jojo's Love Alarm all the time and confuse her), and let Sun-oh and Jojo be happy. And even tried to help their relationship after the crash by sneaking her into the house and so on. 

But when Hye-yeong is finally dating Jojo 4 years after, Sun-oh constantly interferes, follows (basically stalking) Jojo around and even forced a kiss on Jojo. Sun-oh is not respecting her, her boundaries or HY at all. (If this was me, I would've gotten a restraining order on this guy already.) Also when Jojo constantly rejects Sun-oh telling him she likes Hye-yeong, Sun-oh is so immature and can't accept that fact and is constantly blaming it on Jojo lying, the Love Alarm app or the developer. He is both selfish and arrogant and only cares about how he is feeling and not what the other party is feeling and acts with no regard to either Jojo, Hye-yeong or his girlfriend Yuk-jo.

Whereas Hye-yeong takes it slow with Jojo, respecting her, her boundaries and not pressuring her to do or feel anything and really letting it to be up to her on how she feels and acts. Exactly the opposite of Sun-oh. And when he sees the viral video of Sun-oh and Jojo, he never questions or blames Jojo, only worrying if she's okay. Though I was sometimes frustrated at Hye-yeong for not showing more affection in their relationship. Like, if she is hugging you and kissing you on the cheek, you can hug her back, that's a green light for that it's okay!  But I also really respect Hye-yeong for respecting Jojo's boundaries and never forcing himself upon her like Sun-oh did. And letting her decide when she is ready to kiss him.

I love how the show started in season 1 with Sun-oh forcing a kiss on Jojo and ended with Jojo kissing Hye-yeong on her own free will in season 2. It really shows that girls should be the master of their own feelings and fate and that they should've never be pressured into feeling or doing anything by a guy. I really think kdramas (and the whole film industry in general) should follow in Love Alarm's footsteps; teaching girls they deserve to be treated well and with respect!

@AnnaPudding Thankfully, I am not the only one who see this aspect. :D

 AnnaPudding:

I agree. One should not compromise in relationship but accept them only if you don't mind.

I wouldn't say he manipulated her. I think it's more a narcissistic entitled rich dude thinking the world revolves at him so he thinks ofc she likes him

Why shouldn't Sun Oh be a better choice for Jo Jo?

From Sun Oh's point of view, as soon as he laid eye on Jo Jo, he knew what he wanted and boldly chased after her. He honorary told Hye Young of his intention and actions toward Jo Jo. He did ask Hye Young countless time to admit feeling for Jo Jo so he could fight with him fairly.    He took the beating of Jo Jo's ex-boyfriend to end the conflict between them... he knew by doing so he would take a further step to pursue Jo Jo.... he chose the beating.

Sun Oh & Jo Jo both clearly have chemistry toward one another. ' Their kiss came before love.'  They are a perfect fit mentally... they tell each other their dark secret stories, fears and problems. They had fun and cheerful conversations when they were together.  

Sun Oh stood by Jo Jo's side when the whole school turned against her. He paid for her semester school lunch when he has heard that she skipped lunch because she couldn't afford it... he didn't want her to know he did that. He tried to protect her from bad rumors against her. He respected Jo Jo's wish to not be touchy in front of school mates, until Jo Jo approved of it.  He has loved and protected Jo Jo.

Sun Oh didn't do anything wrong... They got into the accident, he was locked up by his parents and came back few days later to have Jo Jo broke his heart out of the blue... His love life was down hill ever since. 

That's completely UNFAIR to Sun Oh.

Years later with countless options that he had, he still loved ONLY Jo Jo.  He was mad when he knew that he was lied to and wanted to know Jo Jo's real feeling for him.  

Call me a sucker for romance... It should have been Sun Oh. 

Right?? IDC what what happened in the webtoon, but Sun-Oh was everything in the drama. this is what i want to tell ppl. seriously, why isn't Sun-oh a good choice? Hye Young is ok but I mean, JoJo is the real villain

 CityOfAngels:
Why shouldn't Sun Oh be a better choice for Jo Jo?
 Euphoria:
JoJo is the real villain

 CityOfAngels:

Right on!!!!!  I hate Jo Jo for doing that to Sun-Oh.

 CityOfAngels:

Right on!!!!!  I hate Jo Jo for doing that to Sun-Oh.

Everyone's putting the hate on the wrong person smh. Everything is JoJo's fault! Why is Sun-oh the villain?? Jojo is the true villain

The support Sunoh gets is incomprehensible. Seeing comments like he honorarily told  Hye Yeong his intentions? Yeah. He did so AFTER he pressured Jojo into kissing him despite him being fully aware of his BEST FRIEND'S obvious feelings for the girl. Sunoh is the definition of a walking redflag. Broken people should not be together. You need to love yourself before you can love anyone else. Sunoh is incredibly narcissistic but he doesn't love himself because of his family. He depends on others to do everything for him. Even blaming Hye Yeong for moving out and saying he was a liar and he betrayed their friendship. When it was Sunoh who literally cucked Hye Yeong. You know what's honorary is when Hye Yeong left Sunoh and Jojo alone despite his feelings for her. He even supported them. Meanwhile Mr cuckmaster decides its a great idea to force a kiss on her 4 years later when she's with Hye Yeong. The man is selfish. He doesn't take into consideration Jojo or Hye Yeong's feelings.

But did JoJo tried to stop him? she even said she wanted it. Desire before love or whatever that original line was. Suoh never got the closure he need. Its common courtesy to the bare minimum. Jojo's just a bitch who doesn't deserve any of them
