New readers: Seungho is emotionally fuc*** up from trauma, and he can't understand a) why he's annoyed that Na-Kyum won't be passionate towards him like Na-kyum is towards In-hun and b) why using his superior social rank and forcing Na-kyum to have s** with him isn't making Na-kyum passionate towards Seung-ho the way he had been when he thought Seungho was In-hun.
The answer to a) is that Seungho is jealous of Na-kyum's love for In-hun, but he's emotionally fuc*** so doesn't understand his own feelings. And b), Seungho doesnt understand the difference between sexual obedience through social rank vs earned sexual affection. And Na-kyum is not simply gonna submit to him just because Seungho is a powerful lord forcing Na-kyum into s**, even if it would make life easier for Na-Kyum. Na-kyum is incredibly brave and strong for continuously standing up to him as best he can.
I know it's horrible right now but it does get better as Seungho figures out he's acting like a massive c*nt and grows to trust and be more considerate of our sweet Na-kyum
