I'm sorry I've to be this harsh on the drama despite loving Taiwanese BL but this .... This is way below average.

Story was fine, I mean I don't mind the whole age thing, i mean it isn't a big deal, one is in high school and the other college that's what? a few years age gab. Well, kids In high school have sex so what? If it was between two high school kids I don't think people would mind so what is a few years older.
However, my biggest complaint is that everything is very forced, I see no reason for the two leads to fall in love? Moreover the second lead, one is mourning and boom! Suddenly in love all over again.

Acting was terrible, it's not abhorrent or unwatchable per se, but it's very inconvenient, chemistry between all characters is nonexistent, even the two brothers doesn't seem like brothers, and the second lead story is extremely forced beside being unrealistic.
So there is literally nothing to look forward to while watching, not even a side story, not even two brothers funny frienemosity. Nothing!

Also, I didn't like any character, I couldn't feel any connection for them, and I didn't care about them at all, making finishing the drama a chore.

Overall skip it, even if you are - like me- a fan of Taiwanese BL, this one is just bad ~
