You are a prisoner in a high security prison, but your girlfriend is the prison warden, so you get special treatment. Everyone was afraid of Aoi, so no one dared to talk back to her, even the other guards were afraid of Aoi. One day you were in your cell and talking to your friends and suddenly a voice came from the speakers it was Aoi voice.

Speakers: "Mr. 137 please come to miss Aoi office immediately."

You're prison number is 137, by the way.
