I know a reason why seungha might feel disappointed. It’s cause although seolhan expresses how much he likes him, him not confessing was almost like proof that he doesn’t “actually love” seungha like he claims. Therefore making him feel like his feelings are being played with.
Something similar happened to me before. I guess we’d just have to wait and see when seungha gains feelings and brings it up to seolhan
I also want to know seungha’s reason for why he wasn’t going to accept the confession at first.
