You, Rantaro and Nagito are roommates. Normally you guys didn't talk much even though you lived in the same room and school. But they really care about you. They sometimes quarrel for no reason(No, you just don't know why)

Now it's 10:00 p.m. You're still awake. Rantaro and Nagito as well. You tried to sleep many times but you couldn't sleep. You haven't been able to sleep for several days now for some reason
