Story:

Well, there is not much of a plot going on, which is kinda regular thing for bl-dramas set in high school or university about two cute boys meeting each other and falling in love, so i wasn't expecting much in this regard. But the show surprised me, turning a bit trivial story of fake-dating into one of the worst screenplays i've seen in bl-drama.
The two main characters are pretty inconsistent in their actions and motivations, especially towards the end of the show. It's clear that their relationships were portrayed in a certain way in order to appeal to general public more, and it was, obviously, successful, considering how popular the show was and is. For me personally, the absence of any queer themes from the main story was very off-putting.
Pacing is a bit weird, though it is definitely not the worst part of the whole show.
Secondary characters are quite boring and single-dimensional at the best, and all girls in the show have absolutely no personality or purpose besides being a cheap plot-devise to make main leads jealous or angry.
Humor is questionable — sometimes it made me smile and laugh. sometimes it made me cringe, but i guess overall it was somewhat okay, though i really hated how green was portrayed as a somewhat stereotypical feminine gay man and basically used as some kind of laughingstock at the same time.

Acting:

Win did a pretty good job as a newcomer, his acting had its ups and downs, and he was by no means perfect all the time, but it was okay. Bright, as more experienced, on the other hand, looked pretty weak in comparison. His acting felt a bit forced and unnatural even in the beginning, but it got noticeably worse towards the end of the show. Chemistry between them was kinda there at the beginning, but completely disappeared by the episode when they started dating.

Music:

It's good. Like really good, the best part of the show, probably.

Rewatch value:

I wouldn't rewatch it unless someone paid me for doing it.
