Su Yijin, once an orphan from the slums who made a name for herself through sheer ability, dies and is reborn as an ordinary girl from an unremarkable family. Though the family is not wealthy, her parents are kind and the family members care for one another, allowing her to experience the warmth of home for the first time. Meanwhile, the vast business empire she built in her previous life and her loyal former subordinates still answer to her. Thus, anyone who tries to disrupt the family's harmony—from coworkers who make things difficult for her parents to relatives who bully her family—will be dealt with one by one as she secretly mobilizes wealth and power, all to protect the peace of her ordinary little family.
