Sister Lin Xi, who grew up in the countryside, wants to repay her parents' kindness by marrying Lu Tingshen, the heir to a business empire who is rumored to be "disabled, gloomy, and violent" on behalf of her arrogant sister Lin Wei. After marriage, she discovered that her husband's disability was a disguise, just to resist family control. Under her careful and gentle company, Lu Tingshen gradually let go of his guard and truly fell in love with this "substitute bride".
Lin Wei, the younger sister who was supposed to marry into a wealthy family, was completely consumed by jealousy and resentment after learning that instead of suffering, her sister was favored by Lu Ting. She began to use any means to spread rumors and frame up, trying to take back everything that "belonged" to her.
However, an accidental medical test revealed an even more shocking secret: Lin Xi and Lin Wei were mistakenly carried in the hospital. Lin Xi is the real wealthy daughter, and Lin Wei's biological mother is the exchanger who had evil intentions back then.
After learning the truth, Lin Wei went completely crazy, and the verbal frame-up escalated to the point of life and death. Lin Xi, who had always been forbearing, finally completed the transformation from "atoner" to "defender" with Lu Tingshen's unconditional support and love. Joining hands with her lover, she not only wants to fight back against all frame-ups with wisdom and law, but also wants to take back the life that was stolen and make the perpetrators pay the ultimate price.
