Arfen Academy accepts outcasts, those who have become objectionable to the kingdom and their own families, becoming both a prison and a fortress for students. When a new student is a dragon who can't control his power, it's just a headache for the academy. When next to him in the same room there is a girl who pretends to be a guy, hiding from the reprisal of her own family, this is already a disaster. But, apparently, fate wanted the two to be roommates. They have to learn to trust each other, reveal many secrets, go through trials and learn first love.
