Gu Chunlan, chairwoman of the Gu Group, has spent twenty-five years desperately searching for her two daughters and one son who went missing. At long last, she finally finds them. To learn about their real lives, she conceals her immense fortune worth tens of billions and quietly approaches them disguised as an ordinary mother. But she witnesses firsthand how all three children are subjected to debt collection, false accusations, and deliberate schemes. Just as the family begins to recognize one another, her nephew, Gu Minghui, suddenly exposes her identity, bringing to light a shocking secret behind the children's disappearance twenty-five years ago. Misunderstandings over family ties collide with a corporate power struggle. Gu Chunlan and her three children gradually move from suspicion to standing side by side, ultimately uncovering the truth and realizing that no matter how big a house is, without family, it is not a home.
