Waking up in the apocalypse, she found herself bound and gagged. Outside the door, zombies. Before her, a voice recorder. Her past self spoke: "These ropes cannot be untied. Untying them means death." She learned to drink with her feet, to evade zombies by staying still, to survive day after day in her bound state. Later, she discovered that the tighter she was bound, the stronger she became. During her captivity, she didn't panic; she knew that as long as she remained bound, she would eventually be able to exact her revenge.

The summoning circle flared to life, and out stepped not a soft, cute loli, but a cool, radiant elven older sister. Lin Chen, blushing, asked, "Can I tie you up with tape?" Elvira let out a scoff—she had only intended to tease him. The contract was sealed. As he reached for the tape, her power was suddenly sealed within him. Her hands and feet bound, a gag stuffed in her mouth, saliva dripped uncontrollably. She, who should have been in control of everything, could only tremble against the wall. And he, while apologizing, pressed the switch on the vibrator.

Yuri, bondage, discipline. Both female protagonists are adults. After school at Qingkong High School, they were the only two left in the entire building. Su Nuo, carrying a shameful secret, asked to go to Shen Qingci's home. Following her back to the quiet apartment, the moment the door locked, all restraint collapsed. Su Nuo, blushing, presented the cotton rope she had hidden for so long to Shen Qingci, her trembling voice saying, "I want you to tie me up," laying bare all her shyness and desire. Soft cotton rope wound around her wrists, binding her back, outlining her slender form. Each loop was a complete surrender of trust. There was no coercion, no harm, only the gentle restraint and secret heartbeats belonging to the two of them.

Shy Lin Xi had always kept his bondage hobby hidden deep within his heart, living in constant anxiety of being discovered and judged. A sudden gender transformation granted him a female body. No longer able to hide in oversized hoodies, he finally dared to bind himself with rope, walking among crowds with newfound confidence, breaking free from societal prejudice, and embracing his truest self within the embrace of secret restraints.

After being humiliated as a pervert by her ex, she bought a synthetic human. Absolutely obedient, never betraying. He tied her into various poses, made her piss herself with a vibrator, watched her cry uncontrollably, then wiped away her tears. She told herself: This is just programming. Until that day, when she gave no command, he spontaneously embraced her.
