I loved it. I'm gonna keep this review as vague as possible. If you are going into this thinking it's gonna be a typical bl movie then I think it might throw you off. This is not a happy, fluffy or really sweet movie. The characters are flawed and the relationship was messy. The acting though... so good and the chemistry was great. Japanese movies really kill me with their endings though. I won't go into detail, but the ending is implied, but not shown (and I get the ending but I'm just greedy and always want to see a more concrete ending if that makes sense?). There are so many subtle things that really gave impact and understanding to the characters and story. There is a lot of character growth, especially with Otomo towards the end. Honestly, it could end there and be a complete story... but I'd LOVE for a sequel. These messy characters were so engaging. I kinda want to see more of their story.

Someone in the discussion thread did a great analysis of the film that is worth reading once you finish the movie.
