@Zoey in fact he doesn't really love seoho he is doing it for himself, the difference is bihwan truly loves seoho, and he knows seoho wouldn't like something like that and that this isn't something okay to do, and the yellow eyes doesn't even care he just want to feel good by bringing seoho back. That's why they say that to love someone is to let them go, also the things that previously happened are probably all his fault
