In order to open up the mainland market, Huo Yunchuan, the heir to the Macau business empire, set his sights on a key piece of land in Star City, but he met An Shihang, a "nail house" who refused to move. When An Shihang's father's condition worsened and he was in urgent need of sky-high medical expenses, and there was no news about his long-missing younger brother, Huo Yunchuan made a contract: he would fund his father's rescue and help him find his younger brother, and she would become his secret contractual lover until he completed the family marriage or got tired of her.
It was originally a cold transaction. Huo Yunchuan thought he was in control of everything, and An Shihang thought he could bear the burden by enduring humiliation. However, after seven years of entanglement, in countless ambiguous nights and days of alienation, the boundaries gradually blurred. When the contract expires, who crosses the line first, and who can no longer get out? Will this relationship, which began with calculation, ultimately drag them into the abyss, or will it become each other's only salvation?
