You don't spoil your daughter, right? I do!

Gu Hao, a weary corporate slave from the modern world, has transmigrated into a novel he once read. In an instant, he became the young master of the Gu family, the wealthiest clan in Jiang City. However, there’s a catch: he’s not the biological son. A hospital mix-up years ago swapped him with the family's real daughter. The Gu family, obsessed with patriarchy, treats their returned biological daughter, Gu Qingyi, with nothing but coldness and disdain. In the original plot, this neglect causes Gu Qingyi to "blacken," leading her to team up with the story’s protagonist to drive the Gu family to utter ruin. To protect his new life of luxury and avoid a tragic end, Gu Hao makes a desperate vow: “Since you won't spoil this daughter, I’ll do it myself!”
