i think i can answer some questions.
I think it's not that he was necessarily forced into it that caused his trauma, I personally believe it was more coercion than anything. I think it was because of the common theme of both of them afraid of being abandoned. Sungho literally ran away from home for a bit when he thought Dohyun left him. They both really liked each other, but I think Dohyun's consciously-induced apathy really did both of them dirty. If he had only stuck around when he knew he wanted to, he wouldn't have caused most of these events, I think.
The trauma response was a mix of obsession and resentment, yeah. From his point of view, Dohyun left him. In Dohyun's point of view, he convinced himself that Sungho was trying to leave him, so he tried to brush it off and leave first. I feel like he felt that he was just another "chick" to use and throw away for Dohyun. He grew resentful that he was the only person who "valued" their relationship. We know that Dohyun did too, but Sungho didn't know that. He wanted to make him "remember." That's what started this.
I think we really can't say how it ended for Dohyun, Sungho clearly got exposed and went off the deep end, but Dohyun has always been forgetful. I thought maybe his destroying the notebook pages was both done in grief and to protect Dohyun from being implicated. Dohyun was so forgetful that he forgot the one relationship that made him feel something. But from what we've seen, which is mostly his pov, don't think we can confidently say anyone but Sungho was implicated. Nevertheless, Dohyun quite literally did not have ANYTHING going for him. Even if he was implicated, his life probably wouldn't be that different. If you find a panel saying otherwise, lmk.
I think there are some points I missed in the plot which would help me appreciate the story more so I'd really be glad to get some answers abt:
So in highschool, did sungho not like dohyun romantically? Was he basically cornered into a sexual relationship to keep his interest going cuz he wanted his attention? Like I thought he also liked him but wasnt ready to do every sexual thing and was coerced into doing things he didnt want to do... thought that was the reason of his trauma.
Then I supposed like a trauma response, he got obsessed over him? I mean this part is open to interpretations, he could just straight up be an obsessed psycho and this would be his trigger or something like that.
Anyway another thing which wasnt clear to me is how their relationship ended, like did it get exposed? How did it happen? My guess was that sungho's parents read his diary and thus reported it or something like that but honestly I have no idea!
Thanks to anyone who's read up to this point...
