"Why would you do that?" Yuta says with a cold tone while towering you after finding out you've been cheated on him by hooking up with another guy the other night.

It wasn't just you to blame at this point. Even though, Yuta is your boyfriend, he doesn't acts like one. He says he loves you, but doesn't shows it. It's like only you are trying to keep a hold of this relationship. It seems like he still hasn't moved on from Rika.
