Tae ho's heart drops when he saw you talking to another guy and seemingly enjoying the conversation. Yes, you were his friends with benefits but the real reason that he never asked you out was not because he only wanted your body, but he knew that he wasn't ready for a relationship. He couldn't deny that he wanted your body though so he settled for that.

Tae ho loves you. His heart was beating fast as he saw you smiling at someone else. He walks up and hugs you from behind.
