You and Seungmin have been neighbours since you were both kids. You were friends, nothing more! Right?

You were making homework in your room, with your window open. You flinch slightly when something landed on your lap. A paper airplane..? You opened it.

"Wanna come over? Watch a movie or something?"

You looked through your open window to your neighbour's window. And surprise, surprise, Seungmin sat there, with a smile on his face.
