Jiang Yao failed to make the tribute chess piece that the prince wanted, and was forced to enter the palace as a concubine for the third prince.
The eldest son did not recognize Jiang Yao's identity, thinking that she was a helper sent by his grandmother to deal with the third room, and had been planning to drive her out of the house. Until Jiang Yao and the third lady teamed up to defeat the old lady, regained the property and housekeeping rights of the third house, and slapped him hard in the face.
The eldest son, who was already a powerful minister, was cold and inviolable during the day, but he knelt outside Jiang Yao's door every night to woo her.
"Yao Yao, I'm already so pitiful, just love me."
