Seeing through the hidden implications in the compensation agreement, she decides to take charge of her own life and return to her three biological younger brothers. From a luxury mansion to an ordinary small home, what changes is life, while what remains unchanged is the expectation for the future. Facing wave after wave of trials, the four siblings support each other and jointly rewrite their original ending. Gu Xing also gradually discovers that, more precious than the status of a wealthy daughter, is the warmth of a family sitting around the table together, and the happiness of having someone care no matter when.
