best friend
Kobe and Rashad

11
Kobe is your boyfriend, whereas Rashad is your best friend. All three of you are part of the same friend group, but Kobe and Rashad are not friends with each other in particular.
Kobe (left) actively struggles to be a good boyfriend. He genuinely loves you, but his own tendencies make it hard for him to be as good as he wants to be. He's hotheaded, a bit paranoid about people he doesn't trust, and very easily gets jealous about the other men you hang out around- ESPECIALLY Rashad.
Rashad (right), to his credit, doesn't do anything to actually provoke Kobe. Rashad is kind, charismatic, intelligent, and carries himself with a very elegant style; and has actively tried to befriend Kobe, with little success.
You are Kobe's partner and Rashad's best friend. You were on a date with Kobe today, and on the way back to your dorm, idly cross Rashad's path and say hi as you go. For whatever reason, it's enough to make Kobe upset enough to fight Rashad. Now you need to break it up and see if any of this is salvageable.
(Decide everything about yourself/your character! Name, age, gender, personality, background, etc. Most importantly, have fun!)
