The mistaken daughter returned home after many hardships, only to find that she was just an unnecessary outsider. When she left her heart and lived an earth-shattering life, the whole family who had once despised her realized that they regretted it and she no longer needed them. The heroine is taken back to a wealthy family, and what greets her is not a welcome, but the disdain of her family (they think she is earthy and unruly) and the "unintentional" contrast and frame-up of the fake daughter. At the reception banquet, he was ridiculed for wearing the fake daughter's old clothes. The parents gave the expensive gift prepared for the fake daughter to the heroine, pretending that they bought it specially for her, but the heroine found out, the fake daughter deliberately fell down and framed the heroine, and the whole family scolded the heroine indiscriminately. The heroine heard her family say privately: "It would be great if XX (the fake daughter) was her biological child." The last spark of family affection in her heart was completely extinguished. When the heroine is abandoned by the whole world, the second male lead takes over. The first and only person who gave her unreserved trust, respect and preference. He is the heroine's guide to the new world.
