Soooo

I think it's the second one, he himself knows that having feelings for his abuser would be crazy yet.... oops ╮(￣▽￣)╭
He probanly forgot about that learned ass long time ago lol

I think Nakyum is in denial. He def doesn't like In-hun anymore since he knew he was being used and he started siding with Seungho, like when he didn't want to be a spy for In-hun. I'm p sure he only said he was staying for In-hun, but he's really staying for Seungho.

I think Nakyum is on the denial stage because he loves Seougho but denies it because hes hurt him so much
