Before Xu Sui's adoptive mother, Zhou Lan, passes away, she leaves her an inheritance of 32 million and instructs her to conceal her identity and pretend to be a destitute orphan when she goes to the Song family, so she can test the sincerity of its members. Xu Sui puts aside all her privileges and deliberately disguises herself as poor, quietly observing people's true nature through life's ups and downs. She wants to discover who will genuinely accept her without expecting anything in return, even when she has nothing.
