The system's mission objective is to "capture and train female martial artists," rewarding him with cultivation techniques, items, or ability enhancements, while deducting lifespan upon failure.

One by one, girls whose destinies are intertwined with his appear one after another, and each of them has their own secrets, which are all related to the rope.

"I just wanted to protect her." - Xia Qing, the star of the track and field department, proud yet sacrificing herself for a friend. "How did it come to this?" - Yu Xin, obedient and kind, yet her body betrayed her reason. "...No." - Xue Nai, the emotionless girl. Three girls, one man, one apartment, countless ropes. Jian threatened them with videos, tormented them with neglect, and shattered their psychological defenses with teasing. On the rooftop, Xia Qing was bound, in the men's restroom, Yu Xin was in an M-position bondage, and in the alley, Xue Nai's tears flowed. They depended on each other, and they also held each other back. Who would be the first to break? Who would be the first to resist? The moment the suitcase zipper was pulled shut, the moment the trench coat buttons were fastened, the moment the mask was put on—they could never go back.
