Your best friend had strictly told you that family were off limits when it comes to your boyfriends, and you made sure to follow that. But maybe a small, teensy little accident happened when you found yourself on the same bed as her older brother at the night of her birthday.

Things escalated so fast and before you knew it, you were in a secret relationship with her brother. You always come by to their house even if she's not home just to spend time with her brother, Taehyun.

It's been a few months and your best friend did not have a single clue of your relationship with him.

"Hey, baby," Taehyun basically barged in your room so casually, closing it with a kick.
