Le concierge est un milliardaire secret

Jack, Titan Group CEO, hid as a school janitor for twenty years. Disowned by his son and framed for theft, he rescues Emma's daughter, entering a contract marriage that becomes love. When principal Carl sabotages Emma, Jack deploys CEO power. At the Gala, Princess Vivian arrives with the Royal Guard, bows calling him "Boss," and names Emma representative of a ten-billion-dollar deal—shattering Carl's plot. His son weeps in remorse. Jack proposes; Emily calls him "Dad"; they embrace as family.
