[1: After Work's End] Aya suddenly senses the smell of chloroform from behind, and when she regains consciousness, she's already bound. She writhes in resistance, but quickly inhales chloroform again. Each time she wakes, she's restrapped, her awareness gradually fading. Fear and anxiety tighten in her chest. [2: The Holiday Trap] Aya, dressed in a white mini skirt and over-the-knee socks, is attacked by an intruder inside her room and loses consciousness. When she wakes, she's seated on a chair, her body tightly constricted. A sinister shadow looms behind her. [3: Night of Betrayal] Tonight, Aya is in her underwear—perhaps a game is about to begin. But suddenly she's assaulted and knocked out with chloroform. When she regains consciousness, her body is tightly bound once more. A night ruled by tension and terror continues.
