Okay, Sena and Shiwoo aside... I just think Hyunwook should end up with Haeyoon. I don't know, it just works out…
He has absolutely no feelings for Haeyoon. When his friend was hoping for them to get together he explicitly stated love cannot be controlled and he has repeatedly told her and behaved in a way to show that he doesn't want to be anything more than friends with her. I love Haeyoon, but I don't they are going to end up together. Ps. on the romance who else is getting tired of his dead girlfriend, they make her seem so innocent when you can get in the first three minutes of the show that she wasn't so angelic.
