Different stories.
IHYV has more comedy elements meanwhile SIY has a heavier melancholic atmosphere throughout the drama.

Both:
- gave the same message about revenge
- have a crime that occurred in the past that have been the driving point of the story and how the male and female lead had their connection

similarities
- main characters who have are in a 'closer than friends less than lovers' /'almost lovers' relationship
- one has participated in a dating show

differences
- ML in Love is for Suckers has always been there for the FL and she is the reason why he participated in the show; whilest in Bakayarou no Kiss, he just saw her on TV after she left the ML's hometown (she always transfers school, that's why they had to separate)

Aside from the similar brand of comedy these dramas have, I see a common character in Baek Ma Tan of Gaus Electronics and Shibata Ken of Mr. Nietzsche in the Convenience Store. Both are both new employees who are ineptly hiding their wealthy background. These dramas are both hilarious so I recommend both if you liked the other drama.

Similarities:
- people wanting to dethrone a royalty
- evil Queen Dowager & state councilor
- strong friendship between a royalty and a subject
- less focus on romance
- engaging story line
- excellent performance of the actors

Differences:
- the story

The Crowned Prince (TCC) is that first sageuk that made me interested in watching such dramas. I usually watch sageuk dramas just to pass time but most do not hold a candle to TCC. (BTW I do not consider Alchemy of Souls as a sageuk drama because it has fantasy elements.) Now, after watching the 4 episodes from Under The Umbrella, I would say TCC has competition.

They have completely different stories but the romance in Gaus Electronics kinda remind me of the one in Love & Leashes. In addition, there's this scene and situation from Gaus Electtronics Ep 8 reminiscent of L&L. If you like office romance, you'll probably like both.

20th Century Girl (2CG) and Our Beloved Summer (OBS) is similar such that both have these elements:
- first love
- male leads are best friends both liking the female lead
- high school setting with their adult lives
- love triangle
- filming & broadcast as occupation/passion

Differences:
- length: 2CG is a movie while OBS is a drama
- the plot

Recommending Gaus Electronics to those who have watched Laughter in Waikiki 2. As mentioned in my other recommendation for the Season 1, both had this brand of humor in failure that as a viewer, we can't help laughing out loud how some situations gets silly and misunderstood. They both have romance too and I would say the couples in both dramas have really nice chemistry.

Recommending Gaus Electronics to those who have watched Laughter in Waikiki. Tbh, I had a hard time finishing the first episode of Gaus Electronics since I disdain verbal abuse and seeing people physically get hurt for nothing (although this was kinda unintentionally self-inflicted, but was kinda caused by his officemates). Just saying I didn't like in the first few parts of episode 1 but come episode 2 and I am laughing out loud like I had in Laughter in Waikiki. If in Laughter in Waikiki, they had 3 struggling tenants not just financially but in other aspects in life, Gaus Electronics is centered on officemates who are in the same marketing team who is known for being a terrible team in the company that are usually prone to failure. Both had this brand of humor in failure that as a viewer, we can't help laughing out loud how some situations gets silly and misunderstood.

If you already watched Koi Desu, What She Likes could be a better or an alternative ending for the story for Shishio & Izumi. To be honest, I am torn with the ending they had whether it is even a good or a bad one.

On the other hand, if you already watched What She Likes, Koi Desu features a story similar to Jun but has a different reason why they want a relationship. I was struck with the conversation they had in the laboratory (the one Ono overheard/eavesdropped) and I feel like there is a similar conversation in Koi Desu. If you like watching people with such depth about getting into relationships, you'll probably want to watch Koi Desu.

They are similar in that both of these dating program is centered on love and friendship. They only differ in that in Between Love and Friendship (BLF), the participants are a male friend group of 4 and a female friend group of 4, meanwhile in Edge of Friendzone (EF), we got 4 pairs of "friends". Also, in BLF, there is no MCs/panel that reacts to the group interactions. (I'm fine with or without but I have to say, the panel of EF is too hyper for me, I mean we got already a very hyper cast member and when we got loud reactions from the panel, it is just too much. BTW, I adjusted well in the 2nd episode, can't drop this, it is so fun and interesting.)

Both dating shows gather a pair who are 'friends' in a beautiful villa where they can meet new people they can fall in love with or confirm/ignite their feelings for their 'friend'.

For the differences, in Love & Joy, we got the Enjoy couple interacting with the participants and facilitating the program meanwhile in Edge of Friendzone, they have a panel who reacts to their interactions. They also have their own unique system of participants showing interest with the person s/he chooses.

Atm, Serious About Marriage (SAM) hasn't been aired, but just reading from the description, this show reminds me of Love is Blind: Japan (LIB:J). Both dating shows have the end goal of marriage and after liking the endgame couple(s) for LIB:J, I am excited for SAM.

They differ in the format and duration since LIB:J has 10 days to know their partners blindly (through a pod with a wall blocking them from seeing the other person) and after the proposal, the formed engaged pair will get to know more of each other by living together for 3 weeks. Then after that, they can get married. So in contrast to LIB:J which had a duration of month for the participants to date, I think SAM would be less rushed but tbh, it is still kinda rushed?. But I'm here for the journey.
