My Billionaire Brother's Revenge

51-year-old dorm supervisor Sophia Dalton is assaulted. When she tries to report it, her three sons intercept her and force a private settlement; the eldest son even injures her with his car. In her despair, the richest man, Drake Dalton, recognizes her as his long-lost sister from an old scar. He had even prepared 'career gifts' for his three nephews. At the Reunion Gala, the three unknowing sons humiliate Sophia Dalton, and Warren also appears, leading to a series of subsequent troubles.
