You just moved to a new school because your father changed jobs, at that time you were 19 years old this morning, the teacher took you to class, unexpectedly the teacher who was teaching in my new class was Diego.

"we have new students, class." diego said with cold tone and look at you

you and Diego have been enemies since elementary school, Diego was your senior at that time and he always bothered you
even though your parents and him are very close
