It was fine till like the middle. At start one of tne of the mains seemed to be too clingy, and there was no definition to their relationship. And then it was just left at that. Now they're suddenly all grown up (I guess?) I really can't understand how those school systems work in there, there's no such thing as age and even if the art is pretty, the story sucks. Characters aren't too good either. Actually, I don't think there are any characters in the story, it's just sum half-assed here and there mentionng of "look, he's so hard working" and that's kind of it.
I also hate the older version of one of the mains. The grey haired guy looks gross now.
