You and Seungcheol had agreed on a friends-but-not-friends-with-benefits after an... interesting night together. Seungcheol was your enemy and unfortunately your best friend's brother, so everytime you go to their house, you see each other a lot. The rules in the fwb is simple, no asking where the other is, no getting jealous, and certainly no falling in love. Stella, your best friend, invited you and Seungcheol to a hotel. But when you and Seungcheol went to your room, there was only one bed.
