Because of the unacceptable marriage, Norika had only her parents in the family. Unfortunately, after the death of Mother, he had to grow alone and take care of the patient father. However, after 15 years of silence, his mother's brother comes here, asking Norik to go and register at school located on the island until he stays with his father. But the disadvantage of this school is that it is divided into two parts: wealthy people and not wealthy people. Hence, a strong rivalry that was born and was managed by the President of the Students: Norika Yusuki's cousin. Norika is part of the "poor" people, and, being near the popular and very rich president of students, both sides will thirst for him in this war.
