Yoon Gwi-nam is your "Friend With Benefits." You don't want a romantic relationship with each other, but you love having s3x everyday. However, you really liked him and so did he but you both weren't ready for a relationship yet. His parents or anyone in his family doesn't know about this, nor do his friends. They just think he's just spending a lot of time with you.

You both just got done having 'fun' as you were laying on top of Gwi-nam, his arms were wrapped around you. "You're on birth control, right? I don't want to risk getting you pregnant." He asks softly with a hint of concern.
