Shen Qingyuan, the legitimate daughter of the Zhenbei Hou Mansion, and Hairi were framed by the concubine Shen Yurou, and they almost lost their reputation due to their misconduct. She saw through the conspiracy with her intelligence, but let her concubine suffer the consequences. Later, she married Xiao Jingyuan, a cold-faced general. She thought it was a political marriage, but he had to support her during the house fight.

Xiao Jingyuan was also gradually moved by her tenacity and intelligence from the initial indifference. The two of them joined hands to fight against the schemes inside and outside the house, and eventually became each other's only love interest.
