Sigh

They're not the same. Na-Kyum is an absolute sweerheart and would be healthy for Seungho. Seungho is the only problem here, he's dangerous and a rapist. Na-Kyum only needs psychological help because of what he's done to him whereas Seungho was crazy from the start. He's unhealthy for Na-Kyum.

NaKyum is a sweetheart, I agree. However, he has been to traumatizing stuff BEFORE the shit Seungho put him through. I feel he still need help around those things. I especially feel this way judging off what the sister has said. he probably do really like and probably want to help Seungho, but I think there is some trauma he need to deal with himself to make sure his feelings are healthy (don’t know if that’s right) and make sure himself is healthy enough to heal another.

His only issue was self internalized homophobia. If Seungho had treated him with respect and care, that issue would have resolved itself pretty quickly. In fact, it pretty much did despite the circumstances. NK now accepts his homosexuality even though there he went about it the wrong way thinking he was a whore because of what his teacher said and because Seungho treated him like one.
My point is that no comparison can be made between them. Seungho seeks to hurt other people, Na-Kyum doesn't. Na-Kyum doesn't have the will to mistreat anybody, Seungho does. He's the only one that needs help although even if he does get, he still wouldn't deserve to be with Na-Kyum after all he's done to him.

I fully agree with you, however, I have noticed that Nakyum (although he is an absolute sweetheart that deserves the entire universe) unwilling brings out what's worse in Seungho (even tho he's an ass by definition). So they're both kinda toxic for each other, even though Nakyum hasn't done a single thing wrong
