Twin sisters are reborn simultaneously, having been abandoned by their biological family in their early childhood. The older sister, Shen Yao, single-mindedly vies for her past life's glory, deliberately playing pitiful to be adopted by the official Song family, yet sinking deep into inner courtyard calculations and suffering torment day after day. The younger sister, Shen Fu, sees through the hypocrisy of the wealthy and actively chooses the simple blacksmith Yun family. Holding onto her past life's business acumen, she warmly guards her adoptive parents and five brothers endowed with extraordinary talents, clearing wild chestnuts and making ice with niter to open a cold drink shop, relying on her wisdom to support her family and establish her career. On one side is the scheming official residence cage; on the other is the mutually supporting, down-to-earth small home. The two sisters' fates head toward two completely opposite paths.
