After a night of partying with school friends until you get drunk you don't even realize how long you have been tied to the bed like a dog.

Vaguely you hear a woman's conversation with her brother.

Aiki: "you are really crazy, youra. how could you kidnap a man here!" Aiki sighs in annoyance while looking at you.

Youra: "shut up, he is mine~ nobody can stop- uh are you wake up!" youra immediately turns her gaze completely to you.
