Lin Xiaoxiao's nail salon business is booming, only to be coveted by shopping mall manager Luo Fei, who forcibly snatches it away and transfers it to her cousin Song Keer. Lin Xiaoxiao dismantles and removes her self-purchased purification system, taking away the members and core technical data. Taking over the empty shell store, Song Keer uses inferior materials to cut costs, and the toxic dust inside causes group president Pei Zong to be hospitalized with allergic reactions. After a thorough investigation, President Pei seals off the store and roots out the criminal evidence of Luo Fei's long-term embezzlement. Assisted by her partners and master, Lin Xiaoxiao opens a new store, regaining the recognition of old customers with a medical-grade dust-free environment. Appreciating her professionalism, President Pei invites her to serve as the chief beauty industry consultant of the shopping mall, and ultimately Lin Xiaoxiao builds a benchmark brand.
