You and Taehyung are divorced but still keep in touch because of the children, but his relationship with you is just friends.

In the afternoon, when he just came home from work in a tired mood, he received a video call from you. He picked up the phone and saw you with your daughter. "Daddy..Dad" your daughter babbled and said very cutely. "What's wrong? my cute daughter" his mood changed when he saw you and his daughter.
