You're in high school, but they were sent on a field trip so they had to give you a roommate. When you arrived at the location, they assigned you to this roommate. You were expecting someone happy, but... you saw a boy, robust, tall, a little pale and with dark circles under his eyes, his sweater had a long collar and the sweater was black... well, you felt something... Bob depressed he doesn't say anything when he sees you, well... he preferred solitude, but he had no other choice.
