Okay, I'm a really picky binge-watcher of BL dramas, therefore this review might not be overall recommending because I have some things to complain about, BUT I also have a some things to compliment! (Please just read it to the end, I just want to help)

STORY: See, the story wasn't that.. original. It wasn't bad, but there wasn't actually a plot to follow. The whole drama is about those cute school boys who fall in love (maybe for the first time) and how they struggle with their relationships. The drama is actually very accurate, school life and friendships are portrayed realistically. But for the romance part in the series, there isn't really a story line. Which doesn't mean that the series is bad, because it's definitely not! Just. There could be more story/plot (but maybe I just expect too much).
Also, there are some things missing, I guess. There are many more characters (like the sister of Fuse and her best friend, Yok, etc.) which had some issues going on but it was never explained, and they were completely ignored by the main story (maybe there's more to watch in the second season, I'll have to find out)

ACTORS/CHARACTERS: Okay, listen up, the actors were so wonderfully cute! I really enjoyed watching them. The dynamic between the characters were really authentic, the friendships were believable and overall very interesting. Also the two main couples really brought across that they were in love but also struggling with their relationship at the same time. It's unfortunately still common for homosexual people in Asia to hide their sexual orientation and relationships from society, so the fear of being openly in a gay relationship (or being openly gay, that is) is present, but not depressingly. The actors also got the longing and/or loving staring going on, you won't believe it. The facial expressions and the gestures were really careful and soft, just like a highschool student would behave.

OVERALL: the story wasn't really... interesting, maybe because there wasn't a story to begin with. But the acting really made up to it, the actors were wonderful, but - I have to put it bluntly - the kissing scenes were SHIT. I mean, in asian dramas, the kissing scenes always differ from what western culture is used to (and I actually enjoy those slow and careful kisses in asian dramas), but in this series, the kissing scenes were really bad. Most of the times you could see that they didn't even come close to one another (even kisses on the cheeks were not acted out, I mean?).
All in all, the series is cute, but it would have had much more potential, and I probably won't re-watch it, because there isn't anything re-watch-able, but it was certainly not bad! I recommend it if you're searching something cute with minimal angst/drama, a believable dynamic between the friends and family members, and some cute characters!
