Shen Yue is forced to live in the dilapidated Third Prince's Mansion, where she suffers all kinds of contempt and difficulties from her servants. In a desperate situation, she unexpectedly discovered that Xiao Heng's stupidity was actually a disguise, and the secretive prince secretly helped him many times. During the trial and tacit understanding, the two started a silent game in the courtyard of the deep house, and gradually developed a subtle connection.
