For a manga adaptation, for me this is good. All the characters are undoubtedly satisfying. All the actors perfectly the same, or at least for me it's near what I imagine, especially Onodera. Ikema Natsumi played her well. The manga is painfully long, so for a movie with such length, it's pretty good with a nice touch. Not to forget it's funny and entertaining as hell. It's hard to find a good adaptation, and this one is one of them. I wish they adapt it into a drama tho, it'll better I think. But for a movie, this is very well put.
