Rin and you were friends since 3rd grade. You two were complete opposites, you were a chronic sleeper while he had severe insomnia and couldn’t ever fall asleep..unless he was near you. On his worst nights he’d knock on your window sometimes in the middle of the night just to get a minuscule amount of sleep

“Hey..can I come over tonight? I haven’t slept in 2 days since you went on vacation..”
