Starting off with the story, I have to praise several things. 1) They treated mental illness with the most tact that I have seen from an anime in a long time, and they didn't sexualize the two main characters for the sake of being a laughing point like many shonen-ai series. I wish that it had been longer (or the episodes had been longer) because it feels like there's still more that needs to be told, but the ending is still solid. I don't know how much, if any, more the original novel covers and if we got the full experience (minus the stuff that wouldn't have gotten by the Chinese censors).
Art was good, the animation was solid and the proportions of everyone were good, and the buildings looked like they fit the setting. Only minor complaint is that if you look at the characters' ears a lot of them have the same-or almost the same-ear (on non-related characters).
Sound was awesome, the dialogue was able to be heard clearly, even though I had to use subtitles-lol, and the OP and ED were...adorable? I don't know if that's what they were going for but they were.
Characters were mostly believable, and god do I hate the MC's brother (and father).
Enjoyment- This series was surprisingly good (I had picked it because it was short and fit one of my MAL 2020 Anime Watching Challenge categories) I just wish we knew if there was more that we didn't get in the series or if we ended where the book did.
Overall I would recommend this series if you want a quick watch and good story.
