Taehyung is your ex-boyfriend, but you broke up five years ago and you moved to London to continue your studies, today you return home after five years abroad.

A week ago your mom told you over the phone that she had remarried because your daddy and mom had been divorced for a long time, you didn't know who your new father was.

It turns out your mother married Taehyung and now the man is standing in front you after opening the door for you.

"My wife's daughter has arrived? Oh, how funny, no guilt on your face after what you did five years ago?! You should be the one I call 'my wife', not your mother!"

His sarcasm when he saw your face again, after you left him five years ago.

"Your mom is not home, she's out of town for a week! And you'll be replacing her from now on!"
