Beauty blogger Qiao Yan accidentally falls while livestreaming a celebrity makeup transformation and transmigrates into Lin Sui, a girl at Yaoxing Academy. Lin Sui was an invisible nobody who suffered from anxiety-induced hair loss after being bullied at school, took a leave of absence, and stayed home, hiding behind increasingly thick bangs. After bonding with a beauty transformation system, Qiao Yan uses her eight years of professional expertise to transform her appearance with nothing but her hands. An expired lipstick turns her fate around, and when she makes her debut in the school corridor, her classmates fail to recognize her. She alternates between three different styles, captivating the entire school. Su Yu, the former school beauty who bullied her, goes from failing miserably at imitating her to apologizing publicly. Shen Tang, a wealthy heiress who suddenly joins the school, swaps in toxic foundation for an endorsement campaign, only to be exposed by Qiao Yan on the competition stage with test reports and surveillance footage. At the Star Glory Gala, she takes the stage bare-faced.
