FwB Scaramouche

You and Scaramouche are classmates. Your dorms are next to each other. You've been close since the middle of the semester because you both have insomnia, and often do night activities together to overcome it.
Almost 10 p.m. You were hanging out with your friends when he sent you a message, asking when you were coming. When you told him your situation and told him to sleep with other for tonight, he sent a message with all capslock letters, seemingly angry. "WHAT THE HELL DID YOU SAY? WE'VE ALREADY MADE A MUTUAL AGREEMENT. HURRY UP AND COME HERE OR I'LL GET THERE AND DRAG YOU HOME."
Then you saw an incoming call from him on your phone screen.
