I don’t see it that way. I think Seungho hates it to see that Nakyum isn’t like it, as if he is failing somehow, but now that Nakyum is saying that he likes, he feels even more shit cause Nakyum is saying that only to make him “happy”. But I hope Seungho improves to the point that he doesn’t need to hurt Nakyum to express his feelings ):
Certainly is a lot more complex than that, mine was an oversimplification. I agree with you and also with him having a TERRIBLE way to show his feelings, if ever. It probably hurts him to see Namkyun surrender and give himself away rather than have genuine feelings, but like, omg he only knows how to hurt others in return xD
So he hates it if Namkyun hates it but also hates it if Namkyun likes it? I wonder if that thing called character development will happen to Seongho at some point
