I think he legitimately doesn’t know how. He’s a noble, which in this story means he can do anything without consequences. He literally killed someone with multiple witnesses and no one cares. Anyone raised in that environment would have an insane sense of entitlement and a few screws loose.
Neither of these characters would know a healthy relationship if it slapped them in the face. I think that’s why many of the darker (confinement, rape, etc.) elements work so well in this series. They literally don’t know any better.
I don’t think Nakyum has yet. He started the series as a drunk (no longer painting due to Inhun’s influence), with just about nothing. Nakyum stayed and painted for Seungho because he promised to help Inhun and raise his status. Nakyum thought Inhun would take care of him in return (terribly naive because Inhun didn’t approve of the paintings in the first place).
When that went to shit, Seungho was all Nakyum had left. I think he’s staying out of self-interest (for now.) Season One was about Seungho falling for Nakyum, but I think Season Two will be about Nakyum falling for Seungho.
Is no one going to talk about how Seungho TOLD Nakyum to eat HIS food???
That’s a seriously major act of intimacy. Seungho would never, ever, EVER let Jihwa or anyone was me do that.
He’s in loOooOooove.
