Shen Zhili, the crown prince of Beijing's top wealthy family, and Su Manxi, the daughter of the Su family, have been at each other's throats for many years and are known to be bitter rivals. An exchange of family interests forced the two people who should have been separated from each other to be bound to a marriage agreement. During the secret marriage, the two made three rules: not to interfere with each other, and to make fun of each other when the occasion arises. Shen Zhili even scoffed coldly: Even if I were single for the rest of my life, I would never fall in love with her. However, not long after, when Su Manxi was surrounded by various young talents, Shen Zhili completely lost control. He blocked people in a corner late at night, his eyes were scarlet, and his voice was humble and paranoid: Have you had enough fun? Su Manxi, you see clearly, I am your legitimate husband. Everyone lamented that Master Shen's slap in the face was indeed much faster than the agreement being terminated.
