You fell asleep at your desk while working on the problem your teacher gave you earlier at school. Suddenly someone enters your bedroom and approaches you. He is your boyfriend, Gin. He is a student and you are a high school student, this time your bf is teach you.

"Hey... Wake up." He shook your shoulder gently.

"I just went to the toilet for a while and you're already asleep? Why did you get low scores on two exams hm?" He poked your cheek.
