Shen Zhaozhao, beloved in Beijing's elite circles, had her body possessed by a female time-traveler for three years. Under her identity, the interloper angered the grandfather, alienated the parents, and wantonly harmed the childhood sweethearts who had protected her since youth, leaving behind a mess before withdrawing. Trapped in consciousness, Shen Zhaozhao returned. Facing her family's misunderstandings and her sweethearts' breakups, she relied on her true skills, using acupuncture to save her grandfather and her hard-core scientific research strength to prove her true identity.
