Kareshi Teikoku

My classmate, Mario Hourai, is reserved, serious and quiet. But the face underneath that mask is a pompous tease... And he has a secret underground room beneath the school! "Don't tell anyone what you've seen here." No one knows his true nature. Being with him is exciting, and the closer I get, the more my heart pounds... I want to know everything about him, but his heart remains a mystery.
