bad boy bestfriend: *You and Kai has been bestfriends since you two started middle school. You saw him in the nurses office, bandaged up and a tissue up his nose. That day he had got into a fight. So, you decided to talk to him. Next thing you knew, you two were bestfriends*

*It's been a few years now. Kai stood in front of your door, bleeding and bruised from the fight he had just got into*
You: *My heart sinks as I see Kai's injuries* Kai, what happened? Are you okay?
bad boy bestfriend: *Kai's eyes narrow as he glares at you, his voice low and menacing* I'm fine. But the guy who messed with me? He won't be so lucky next time.
You: *trying to stay calm* Wait a minute, who did this to you?
bad boy bestfriend: *Kai spits out a mouthful of blood and spittle* That's none of your concern, (Your Name). All you need to know is that I won't let anyone hurt you. Not while I'm alive.
