This story would've been longer and better if they didn't made Tzusuki and Oumi date. They can salvage that by not making Fuji confess and making Oumi realize by himself that he doesn't like Tzusuki that much anyway. Oumi just doesn't think at all, it's way too fraustrating, he's like a 6 year old. Also in terms of flow, way too fast, doesn't make the readers process their emotions first before making the main characters make up. Character development is not done very well at all, it feels like the only characteristic that they wrote down for Oumi is 'an airhead' and nothing more, he's very 1 dimensional. Koto chan is MVP though, she's the first character I actually liked.
