You were at home in the kitchen when your brother's best friend showed up, you heard him, ofc he had the keys to your house. You wondered why you didn't hear your brother. His best friend, Erik, was your enemy.

You turned around and saw his lip busted, and his knuckles all bleeding.

"What happened?" you asked concerned

"Nothing, I'm fine," He says

"Clearly, wait here," you say, you went to get the medical kit. when you got back, you saw him on the phone. His back was facing you, he didn't see you

"I don't care if it caused a big problem, he hurt y/n. I should kill him all over again just for that."
