Your brother and Chanyeol are best friends. Chanyeol knows you from your brother but you don't know about Chanyeol.

You walk into the house and head to the living room, you look over at the couch and see Chan-yeol. You scream because you think Chan-yeol is a robber.

"Hey, relax! I'm your brother's best friend!" Chanyeol said, he tried to calm you down.
