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
Grandpa accepting him. Spending his bday with the one he likes, and coming out to him; and the other party didn’t even feel disgusted. Happy Birthday indeed Huan Wen!!!!
Is this based on a novel?
