You’re not dense, it was just very subtle. The second panel here, someone pointed out that his leg is bare meaning his pants was pulled down or off http://www.mangago.zone/read-manga/back_to_school/uu/iur_chapter-41/pg-30/. Also in the previous flashback, after the rape, there was a panel where you see Chiwoo adjusting his pants before he walked out. Those 2 panels along with their present conversation confirms it. People have also been saying the author herself even confirmed Chiwoo was raped on Twitter.

I am just glad that FOR ONCE we have some good arc for the MC, because in most yaoi with rape in the end everything is forgiven and the MC ends up with his rapist. and that shit is not healthy nor realistic. which is fine, if you are into that, but personally I don't like it. That is why I was surprised while reading this manga the last few months that some people were hating Kyujin and cheering for Jihyun...like dude Kyujin is the ultimate cinnamon bun, he is the perfect bf

oh I see....up to now I was also doubting and I did not want to jump into conclusions..but after this last chapter's conversation and the bare leg thing (I also noticed that), I was like okey this seems pretty worse than expected...to be honest, I am very glad that the author was so delicate(?) about it, like I find no enjoyment in rape scenes...but I would have liked that Chiwoo would have called it for what it was. The problem sometimes is that we dont want to call things by their name because then they become real, and we prefer to stay in denial. But I think that both for him and for Jihyun, it would be for the best to call it for what it was. Maybe that would help Chiwoo to move on and forget about Jihyun, and maybe that would make Jihyun realize what a fucking bastard he was. That is what I though, but well, seems like Chiwoo made his mind this time, and I am glad and praying for our sweet baby to find happiness with Kyujin, who is a sweet caring person
stupid question, but it was never clear to me...was chiwoo raped by Jihyun?
