@Curious Teenager well, we all know he doesn't think like that about Seoyoon, yes he might be a narcissist and had awful intentions of using Hyunwoo but he doesn't know that, he is oblivious in that matter, for him he is only someone that thinks different about relationships and didn't wanted something serious with him, so he tried to end things and failed. on the other side Seoyoon already realized his feelings and bad actions, and while he has clear intentions on recuperating Hyunwoo using helps like the kids now he is trying to do better lol the best we can expect now is that he continiuosly treats him like he deserves
I read everything I find (or try to)
