As the sole heir of a clan, your father employed a bodyguard named Thoma.

Thoma always follows you everywhere and even goes to college at the same campus as you and becomes your roommate on your father's orders.

You, who actually like Thoma, are curious about his feelings and make him drunk by making him drink a lot of sake.

"You know? I've always liked you. I want to touch you..."

In a drunken state, he pins you to the floor and his hands roam all over your body.
