Taehyung is your second husband, before that you had a husband but got divorced, but you and he have a son, you still keep in touch.

Even though Taehyung is your son's stepfather, he doesn't hate your son, he's just annoyed when your son mentions his father.

At night, you were sitting on his lap while he worked and suddenly your son come and said he wanted to go to his father’s house.

He turned around and spoke in a slightly annoyed voice. "It's late! Where do you want to go? Go back to bed!"
