I have a love-hate relationship with this drama. It started off beautifully and I liked all the characters (except for the ML who was the proctology doctor Dong Go Yoon. I'll explain this in a bit). I feel like the story could've been a lot better if they focused less on the love story between the leads. I also was on the wrong side of the love triangle which didn't help with my enjoyment rating. Aside from that, it was a cute little drama. I liked that it was only 12 episodes and there weren't many filler episodes.
Stop reading if you don't want spoilers ;)

Plot wise, the story was kind of predictable at times. I knew the death of Da Eun's close patient Kim Seo Wan (WHO I LOVED SO MUCH *CRIES*) would be too much for our FL and I knew that she would end up becoming a patient in a psychiatric facility. Obviously despite the predictability, I still enjoyed watching the show unfold and seeing her descent into mental illness/depression and how she managed to recognise her condition and learn to care for herself. The drama made me cry at times, especially with the way the FL was treated once she returned to work by some of the psychiatric patient's relatives and even the way the apartment complex was treating the Head Nurse for trying to move into the building with her sick sister.

Things I loved:

The drama did a fantastic job at showing how each person felt dealing with their mental health episodes. The other male lead, Da Eun's best friend Yu Chan (THE BETTER MAN) suffered anxiety and panic attacks. There were a few scenes where they showed how he felt in that moment by contrasting it to water that would slowly start at his feet and then rise up until it swallowed him whole. Another mother of a patient who was overworking herself had an attack where she was walking in the City and then suddenly each of the buildings started disappearing around her until she was just essentially left in an open white void of nothing. Even seeing the dragons that my favourite character Kim Seo Wan wanted to slay was really tragically beautiful. The visuals in this drama were well done and on point.

I also loved the side couple's romance. I found their love story to be better than the main leads. Truthfully I was team Yu Chan and Da Eun. Friends to lovers is the superior trope and the storyline had so much potential. I would've loved to see them end up together but she went for the most boring character ever. So side couple >>> main couple.

Things I hated/ Weakest part:

Kdramas need to stop romanticising males who stalk their love interest. I really loved this drama and wanted to watch it but every time Doctor Dong Go Yoon was on screen, I felt physically sick . I find it extremely uncomfortable to watch when the ML thinks it's okay to suffocate the FL with inserting himself into her life ALL THE TIME. The scenes where he was waiting for her at the bus stop everyday, letting buses go past and then trying to make it out like he just go there and it was a coincidence that they were both waiting for the same bus didn't sit well with me. I could just be nitpicking and maybe most people would find this cute but to me it really triggers me. I have been in situations where guys come on too strong and love bomb you and essentially suffocate you by constantly being around you and it's annoying. I don't see how Da Eun fell for him. Also his count down until he could ask her out again made me furious. Even when he was told that Da Eun was depressed and not coping too well and NOT to go to her house, he still went with flowers. I'm sorry but he really irritated me. He was also a shit friend to Yu Chan. He knew his friend liked Da Eun and he still pursued her. Even when Yu Chan asked him not too, he didn't care and disregarded his friend. I hated him. I hated his character and he ruined the show for me. I also hated him cracking his knuckles in every scene. I felt sick whenever he was on my screen.

Aside from my rant about Dr Dong, I did like the show and I could've rated it a ten, but he ruined my experience for me and therefore, I probably won't be rewatching this again in the future.
