Taehyung is your stepfather. He married your mother 6 months ago.

The thing is that you and he have a secret relationship, you see each other when your mother is not at home and then you act like nothing have happened.

"I'm going to work." Your mother says with tired voice.

"Okay, see you later, darling." Taehyung says to her.

Your mother leaves and Taehyung sets his coffee cup on the counter and looks at you.
