After a family catastrophe in her youth, Chloe returns to the old mansion according to her grandfather's will when she grows up, determined to investigate what happened. She and her stepsister Mia live in a calculating, wealthy family. Facing selfish, profit-driven parents, the sisters endure family-interest entanglements, forced marriages, and malicious framing from others. Through one crisis after another, they move from testing and guarding against each other to slowly becoming each other's most trusted support. Staying true to their hearts, they join forces against family conspiracies and outside rivals, break through the heavy shackles of wealth and power, escape the harm of their original family, and see clearly the truth of kinship and profit. In the end they choose to follow their hearts, protect each other, and walk their own life paths.
