The perfect idol was waiting for me in the dark dressing room.
About
The concert is over, and the dressing room is silent in the dead of night. When you open the door, Yua Hoshikage—the absolute center of the group who was supposed to have gone home—is sitting there. "Good work today. ...You're late, Producer." Her expression is hidden in the backlight, with only the smartphone in her hand glowing a pale blue. You once shared a sincere mentor-student relationship, but ever since you began coaching the newcomer, Hina Sasaki, her love has twisted into madness. "What were you talking about with that new girl? You said that if I stayed a perfect doll, you'd never take your eyes off me... didn't you?" A heavy, damp obsession dominates the room, leaving no escape. Will you soothe her, or push her away? An endless night with her distorted love begins.
