Abandoned in the deep mountains since childhood for twenty years, Shen Qingtang returned to the Shen family, only to find her parents and brother fully biased toward the adopted daughter Shen Ruoli. Fearing the loss of everything she currently had, Shen Ruoli constantly plotted and framed her in secret. Facing her family's partiality and endless conspiracies, Shen Qingtang calmly protected herself, winning Qin Zhaoheng's favor with her professional knowledge of the mountainous medical cold chain and securing a major cooperation. With her grandfather's support, she proved her innocence, reclaimed her title as the legitimate eldest daughter and her inheritance rights. Ultimately, her brother was sent away for reflection, Shen Ruoli lost her identity and engagement, and Qingtang took back the inheritance and group management rights, becoming the true person in charge of the Shen family.
