TLDR: Seungho is developing, you guys are just mean.
I'm getting a little pissed of by reading all this comments, this is a realistic character development. It would be unrealistic for Seungho to suddenly be all lovey-dovey for Nakyum.
I feel like this forward-backward development is in character. Very realistic and slow paced, as it would be for a person of his psyche in real life.
He is slowly becoming more aware of his feelings but doesn't know how to deal with them neither how to express them.

Exactly thank you!! He’s not gonna right away be a cookie cut lover, profess his feelings to Nakyum and they’ll live happily ever after it’s gonna take some angst before Seungho will slowly start to change. He already has changed compared to beginning chapters and you can see his feelings towards Nakyum are what’s changing him but he’s very confused bc he’s never experienced such feelings before.
