Synopsis：Do-hyeok thought his life was perfect—until his grandfather died suddenly and his mother was framed for poisoning him. A single forged will shatters the family: the penthouse is seized, the accounts wiped clean, and a third‑generation chaebol heir who has already lived one life is reduced to a pauper overnight. Behind it all stands his uncle, Cha Hyeon-seok. But inside Do-hyeok’s mind are the memories of his previous life—the ultimate weapon for revenge. A no-name boy group he meets in a cheap rice-soup joint, a laughingstock entertainment agency, and a desperate one‑billion‑won bet made with borrowed money. In the palm of a ten-year-old’s hand, the board of vengeance is reset. Do-hyeok’s second revenge begins—and this time, who will be the one forced to kneel?
