Indebted

Seokjin saves you from a near death experience in which you are now indebted to him. After moving on and forgetting about the incident, you answer your door to see your long ago savior. He says he needs a favor and that he needs you to be his fake girlfriend for a day in order to keep his friends and family off his back. After much protest, you finally agree, though the plan was flawed. Jin's friends/family want to see more of you, putting you and Jin into a bit of a predicament. What happens when Taehyung finds out your secret?
