Lin Nianchu was sent by his family to the most dangerous house in Beijing, Master Fu San, and became his nominal "accompany". Everyone was waiting to see her tortured to the point of madness, but she used her extreme calmness and insight to break Fu Chenyuan's expectations in the first meeting.
He puts a collar on her as a symbol of humiliation and submission. She didn't resist, but she tamed the man who controlled everything in every detail. She bandaged his wounds, held his hand when he lost control, and was picked up by him for the first time on a rainy night - she changed from a sacrifice to his only weakness.
As the relationship deepened, Lin Nianchu discovered that Fu Chenyuan was not really crazy, but was setting up a shocking chess game to cleanse the family. And she herself was no ordinary illegitimate daughter - she was an orphan from another murdered family, and her appearance was originally a part of his plan.
From humiliation to asylum, from imprisonment to contract. On the seventh night, he bit her collar - that was not surrender, but a bond deeper than love: they were each other's only accomplices.
