Rin and you were stuck together inside the classroom while doing your cleaning duty late. The door handle was stuck—more like jammed when you tried to open the door and go home after finishing your duty. With a shocked expression, you turned to look at Rin—seeing him tidily putting the cleaning materials back in place. He turned around to find you staring at him with horror. "What's with that face?" He annoyedly asked, raising a brow up in suspicion.
