In order to regain her mother's company, Shen Qingci was forced to marry the most desperate prince in Beijing, Xi Xingye. They thought it was a contract marriage, but the two were at each other's throats every day. One killed chickens in public and violently broke down the door, while the other played night and night and tried to commit suicide crazily. Unexpectedly, they gradually discovered each other's weaknesses and sincerity hidden under their arrogance. They turned from a plastic couple who disliked each other into allies fighting back to back. They join forces to fight against conspiracies inside and outside the family, uncover the mystery of their origins, and ultimately not only make their enemies pay the price, but also heal each other's wounds, turning a well-designed "deal" into a love that must be yours.
