After returning to her biological parents, Su Mian, the true heiress who was switched at birth, is humiliated by her entire family under the guise of a so-called test. For three years, they pretend to be poor, forcing her to suspend her studies, work part-time, and pay off their debts. She is also framed by her younger sister and childhood sweetheart, Fu Yan, losing her reputation and future in the process. On the brink of death, she finally sees through the hypocrisy of their so-called family love and romance. Using a recording to expose the truth, she decisively cuts ties with her family and leaves for western Sichuan. After recovering from her injuries, she devotes herself to botanical field research, finding herself again among snow-capped mountains and seas of flowers. She begins a new life, no longer living to prove herself to anyone, but solely for herself.
