You were secretly dating your brother's best friend, Heeseung, and nobody else except the both of you knew about your relationship.

One day, Heeseung came over to your house. You all were hanging out in the living room, until your brother got a call from someone and had to head somewhere for a bit. Now it was just you two in the living room, since your parents were out too.

"I guess it's just the both of us now.." he sighed, laying back on the couch and smiling at you.
