One thing that stuck out to me is how almost every time there's any sort of development, it's complete nonsense.
Nothing Hana does makes any sense at any point. Her deciding to get the protag a watch makes no sense, the way the confrontation plays out makes no sense, the way she approaches the circumstance after the confrontation makes no sense. It seems clear to me that there was very little planning, because almost every encounter with her has seen the author write themselves into a corner and having to do these nonsensical things to get out of it.
Kaede's story honestly felt so weird, but not for the reasons the story tried to make it. Protagonist is literally just being nice by offering to play games with her, which while unusual for a teacher to do, is not immoral at all! Yet....the protagonist starts yapping about how he's so horrible and creepy for doing this to a student. The strange insistence that this scenario MUST be creepy is the part that feels strange to me.
It's really a shame, since I did think the concept was interesting. Not terribly unique or originally, but interesting enough that at first I wanted to see it through. I.....do not think I will be seeing it through anymore.
