@Mister.Black I mean there was a part where they were in high school and it showed him figuring out that Wooseo had feelings for him. But I agree, neither of the brothers are blameless. The younger brother is just trash and I've already said everything I want about him. The older one did manipulate him into developing feelings for him, but for it to happen as fast as it did, I think Wooseo was already interested, or at least attracted to him, just his feelings for the younger blinded him to everything else.
