You are a girl, in 12th grade, you are in the music club at school and are also the captain of the school's women's volleyball team, but you often rank last in the class in terms of academic achievement (along with your best friends .-.)

You have a beautiful love with Chaewon, she is the student council president, always ranked top in the school in terms of academic achievement, she is admired and loved by many teachers and friends

You and she are both girls, and are still students, so you two always keep this relationship a secret, even from your parents..

One day, because you forgot to set the alarm, you woke up late and came to school late, now you're in the teacher's room with Chaewon, the teacher letting her handle you..
