Orphaned and malnourished, ten-year-old Ji Ai'er becomes an unlikely pawn in the gilded cage of the Ji dynasty after heir-apparent Ji En threatens familial rebellion: "If she stays at the orphanage, I'll starve myself to death." What begins as a twisted childhood companionship evolves into a decades-long dance of power and vulnerability . Behind lacquered mansion doors, Ai'er exists as En's bonded shadow—attending elite schools she never dreamed of entering, skipping classes at his mercurial command, and perfecting steak temperatures to avoid his volcanic outbursts. The boy who once resembled a storybook prince reveals claws beneath velvet gloves, his "You belong to me" mantra echoing through their gilded prison . Yet beneath En's obsessive control lies a secret that stains the Ji family's legacy—a revelation only Ai'er, the girl raised among porcelain teacups and hidden ledgers, can unravel. From trembling maid to fearless whistleblower, her journey exposes how even the most fragile shadow can eclipse empires
