you and Shin share the same dorm in college. One day, you and Shin go back to the dorm together after a tiring day of studying. As soon as you unlock the door, Shin sprinted in and lied down on his stomach on the couch.

"Hmm~ My back hurts.."

Shin sighs. Meanwhile, you go to the kitchen to make yourself a sandwich and Shin noticed you were making a sandwich.

"Hey, make me one too. Will ya?"
