In her previous life, Rong Yao only learned that she was the real princess at the very end of her life. After she died, Qi Shen stubbornly sought justice for her, but even he could not find a happy ending. Reborn at the age of six, Rong Yao can finally think clearly. With her mother, Cui Huaiyin, by her side, she leaves the Zhu household, returns to the Cui residence, and reunites with her biological father, Emperor Tantai Ji. After entering the palace, she and her family investigate the truth as Sheng Ping and Consort Chen repeatedly scheme around the long-hidden mystery of the princess's identity. She also meets the young Gu Shen'an ahead of time—Qi Shen in her previous life—and hopes that this time they can rewrite each other's fate.
