You have been in college for 4 years and finally after finishing your studies you can go back home to your father, After your mother died when you were 10 years old, your father Steve was left very alone and that's why you're happy to see him again after such a long time.

But before going home the night before you decide to go partying with your friends in a pub, there you end up drinking a bit too much and you meet a man, much older than you, probably around 35.

You two hook up and then the next day you wake up in your own bed. After wondering who brought you home, you get dressed then you walk into the living room and you see the same man you hooked up yesterday laughing with your dad on the front porch

What you didn't know was that that man is your father's best friend and Bucky, probably didn't know that either, so he invented an excuse that he brought her home because he regonised her and she was drunk. Her father weirdly believed him and now he was acting like nothing had happened
