Xu Xi Xi (Yu Yue), the daughter of the wealthy Xu family, wakes up after a traffic accident with no memories of her past. When she sees her bodyguard …
After a thrilling car chase, the leading car accidentally plunges into the sea, with a young woman, referred to as the young lady, falling into the ocean. Xu Xixi finally wakes up but finds herself completely unfamiliar with her doting father and the luxurious environment around her.
Following Xu Xixi’s successful performance, she catches the media’s eye. In a distant fishing village, the grocery store owner Ding Beifan recognizes her as his friend An Yue and wonders how she became the rich young lady "Xu Xixi" and debuted as a star. Ding Beifan searches for information and contacts the agent Tian Sui but is blocked, mistaken for a harasser.
While on a business trip, Xu Yongyu watches his daughter’s program and grows suspicious, knowing Xu Xixi never had a friend named Ding Beifan. Ding Beifan and An Yue plan to visit the fishing village where An Yue lived to find her memories. They try multiple times to shake off bodyguard Lu Jinyan and finally succeed, unaware it’s all part of Lu Jinyan’s plan.
Late at night, feeling profoundly lonely and missing her mother, An Yue suddenly finds an old phone left on the fishing boat by her mother. The only message tells her that she is indeed Xu Yongyu's daughter and instructs her not to return to the fishing village but to continue living as the young lady.
Tian Sui’s first impression of Xu Xixi is that of an arrogant and domineering young lady who would slap servants. This scene was captured by the gossip reporter Li Feizhang and spread online, becoming the latest scandal marring Xu Xixi’s reputation.
Lu Jinyan learns that Xu Yongyu is about to bring a professional medical team back to the country to conduct regular check-ups for his daughter, which could expose An Yue's true identity. He secretly asks his friend Jiang Tiancheng to investigate the medical team.
