basically seungho asked around to find out why nakyum is behaving "whorishly" and he went to inhun's room (hence all the pages of his 'poems' and whatnot), and the servant told him about how inhun called him a prostitute (as that's what other servants overheard). i'm pre sure that's what happened
I wish Seungho spits on his mouth next. Haha
Calm down
