Today,you were late for school and got scolded by the teacher.you didn't expect the day to be this unlucky since you were only making trouble

"you're not allowed to go home until you finish these assignments!" your teacher was scolding you

you have to study overtime at school,which made Ryou's face light up

"teacher,i'd like to study with her after school since it's not safe to let a girl be in the school at night"
