An ordinary girl named Su Xiaowan pretended to be sick and sneaked into the 'Number One Medical Clinic in the World' to cheat her account in order to help her younger brother seek medical treatment. Xiaowan's trick was discovered by Gu Yanxi, the young master of the Gu family who also came to seek medical treatment.

Gu Yanxi deliberately dealt with Su Xiaowan, a little scammer, by replacing her with his personal maid and making things difficult. Xiaowan was criticized by Aixi for becoming Yan Xi's personal maid, and her salary was deducted by Gu Yanxi for dirtying her cloak.

Xiaowan was held hostage by a group of bandits led by Scar Hui. In a moment of crisis, she was rescued by Yan Xi. The two of them were outnumbered and ran to the dyeing room. When they were at their wit's end, Xiaowan held an umbrella and jumped from the second floor with Yan Xi in her arms.

Xiao Wan was supposed to go shopping by Brother A Ye, but was intercepted by Gu Yanxi and taken to the temple halfway. On their way back to the mansion, the two encountered Scar Hui setting up a ambush and accidentally fell into a trap while escaping.

Yanxi Xiaowan returned to the mansion the next day, and the maidservant of Aixi Hui heard that Xiaowan and the young master had spent a night alone outside the mansion and wanted to arrest Xiaowan for questioning. When Xiaowan hid in Tibet, Ziqian came to the rescue and asked Xiaowan to go to yesterday's appointment.

Memories of Yan Xi's childhood resurface, as she falls ill and falls down. Xiao Wan embraces Yan Xi tightly. Second Young Master Ziqian rescued Yanxi Xiaowan, and Xiaowan discovered Ziqian's identity. Xiaowan visited Yanxi late at night and fell asleep beside her collapse.
