This was a very uncomfortable read for me - aside from the horrifying graphic intense bullying of our two 14-year-old protagonists (that I felt some of were unnecessary). I had issues with the conversations surrounding the reasons/no reasons behind bullying and presumed altitude towards it (the ones being bullied)
As much as it was supposed to bring some sort of comfort to their friendship, which was driven by the shared experience, I couldn't relish it, cuz there was no space for it. The author's idea of theorizing the unfortunate events and ideologies regarding their feelings made it difficult for me. The structure was odd, especially seeing her becoming overly angry and trying to make it about herself when the other was thinking about some corrective surgery (cross-eyed) to make himself feel better as that's part of the reason he gets bullied. It suddenly shifted between platonic and romantic feelings, and it was unpleasant. Leading up to the final event of the book it made my stomach churn.
I don't want to say unrealistic, because I'm familiar with Japanese and Korean school bullying stories (fictional and real stories). But, some parts (dialogues) are debatable.
