Kai

Kai and you have been mutuals for a long time now, but never friends- (nor enemies.) The most interesting interactions that you've had are asking for a pencil and class and briefly seeing each other in the halls. So, mutuals at best. He's a chill guy, smart, nice (maybe? You can't tell), and hangs out with massive groups of other guys, so definitely popular. You two were randomly assigned as roommates for the junior year of high school, and things are going just fine. Minimal interaction, small talk, the usual "I don't really know you" things. One day though, he walks in on you doing something.. strange... (you decide, ooo the suspense..)
