The legitimate daughter of the Su family regrets her marriage, and the concubine Su Wan is forced to replace her younger sister and marry into the Gu family, which is known to everyone. Rumor has it that Gu Yechen is a ruthless living king of hell, and his two fiancées both ended miserably. But on their wedding night, Su accidentally caught a glimpse of a shocking secret - there was actually a game blood bar floating above the boss's head, and her emotions could directly affect his life or death! Fear and scolding will make him bleed and be on the verge of death, but being coquettish and getting close can make him instantly full of blood and increase his combat power.
In order to pay for the medical expenses of her seriously ill mother, Su Wan was forced to embark on a "fancy way to save her husband". She was also signed by Gu Yechen to a bizarre labor agreement, and she was paid for beatings and scoldings. As they get along, she gradually uncovers Gu Yechen's past of being abandoned and system-ridden in his childhood, and she also learns that the two have a life-saving intersection.
Su Yan and the Shen family came one after another to plot against each other, and the crises piled up one after another. The two people who shared their lives worked together to fight back. The cold and tyrannical boss became an exclusive "abuse-seeking" maniac who doted on his wife, marrying a weak girl and growing up against the wind. When the truth of the system and the ultimate crisis come, this marriage bound by a blood bar will eventually turn into a two-way love affair, creating an alternative sweet love between wealthy families.
