Su Waner, the former concubine of the Shangshu Mansion, was framed by the powerful Prime Minister, her entire family was exterminated, and she was exiled to Ninggu Pagoda, where she died with hatred. When she opened her eyes again, she actually traveled through time and possessed Shen Bing, a low-level maid in the Prime Minister's Mansion. Being in the enemy's house, she restrained her hatred, disguised herself as a weak and sensible "green tea", and hid in hiding.
In order to avenge her family, Su Waner (Shen Bing) relied on her knowledge and strategies in her previous life to gradually gain the trust of Gao Shuhua, the legitimate daughter of Gao Xiang, and took the opportunity to get close to Gao Xiang's inner circle and secretly collect evidence. She entered the Marquis's residence as a girl on trial marriage, accurately grasped Xiao Chuan's preferences, and impressed the unfeminine Marquis with details and sincerity.
Xiao Chuan saw through the ambition of the Prime Minister and Su Wan'er's disguise, but was deeply attracted by her tenacity and courage for revenge. From the initial indifference and alienation, he gradually became her most solid supporter. The two worked hand in hand to deal with Gao Shuhua's repeated frame-ups and Gao Xiang's crazy counterattacks, while at the same time dismantling Gao Xiang's treacherous power and collecting evidence of his corruption, bending the law and framing Zhongliang.
In the end, Su Waner successfully teamed up with Xiao Chuan to overthrow the Prime Minister, bringing justice to the Su family.
She also made a counterattack from a maid in the dust to become Mrs. Hou, whom everyone respects. She put aside her obsession with revenge and ran in both directions with Xiao Chuan, gaining a fulfilling life.
