Li Chiying, a 38-year-old doctor of chemistry, Li Chiying, a 28-year-old wealthy housewife, and Li Chiying, an 18-year-old high school girl, woke up in the same body due to an accident. They are "Li Chiying" herself in three parallel worlds. They share the body of youth, but have completely different memories, skills and emotions.
The story begins one afternoon before the college entrance examination in 2016. Thirty-eight-year-old "Aunt" took the lead in regaining control of her body. She changed her original owner's cowardice and publicly molested Ye Xingge, the academic tycoon she had had a crush on for many years, shocking the whole school. The 28-year-old "Queen" then appears. She is calm, suspicious, proficient in finance and self-preservation, and secretly investigates hidden dangers that may threaten her (them). The real eighteen-year-old protagonist can only watch "selves" in her heart subverting her life, achievements and even feelings.
In conflicts and compromises, they face campus bullying, family conspiracy, business traps, as well as the huge family and potential poison behind Ye Xingge.
From the counterattack in the examination room to the American gambling game, from seeing through the conspiracy to accumulating capital, the three "Li Chiying" gradually formed an alliance through the tug and pull: they want to rewrite all tragic futures, no longer sacrifice for anyone, and live only for themselves.
This is a war between three "I"s joining forces to fight against the "I"s of fate, family affection, love and conspiracy.
