Now enrolled in Kuoh Academy as a foreign transfer student, he enters the school grounds... And causes a commotion while doing so.

Y/N was an ordinary boy in an ordinary Co-Ed school, he got bullied a lot at this school, so when the opertunity arose for him to go to another school he didnt hesitate to sign the papers... Without reading the fine print. Upon entering he found out that it was an all girls school he wanted to leave, but he couldn't do that because he signed the papers. He now has to spend 3 years there... But will his talent in music help him along the way? And what else trouble awaits with human trafficking on the rise?
