The story takes place late at night at the largest auction house in City S. A girl is lying on the sofa in a room. The surrounding environment is a mixture of light and dark. When the clock strikes twelve, the girl wakes up. The color of her pupils changes from black to red. Then she gets up and is ready to go out and hunt. At zero o'clock, in the elevator, there is a man and a woman. The two are acting intimately. When the man sees the girl, his eyes light up. He pushes away the woman and walks towards the girl. The girl has red eyes and her words are innocent yet seem to carry danger. The man wants to touch the girl. The girl grabs his wrist. The man becomes angry and raises his hand, but is injured by the girl. Two minutes later, the girl steps out of the elevator. A sudden scream comes from inside the elevator.
