Wait for the end… or, read the novel.
The whole thing is more twisted than it seems.
I’m feeling the same at this moment btw, and people are change, but at the other hand this kind of mistake is can not be cleared with growing up and changing.
I experienced something similar like Juyeon, but I wouldn’t be able to do this many things to my abuser even though he ruined my life for several years.

i can’t help but feel bad for jiwook, despite knowing what he did
this really is complicated, i keep thinking, does he deserve all of this? he doesn’t even remember, i don’t know if that makes this worse though. traumatizing someone this badly and just forgetting it, like it was nothing, when to juyeon his whole life changed because of him. i really don’t know, i feel bad for both and this story is just so, so sad
