Penniless Riley must live in a manor for 15 days to inherit $50 million—but her charge is Luna, a four-meter giant baby. Hunted by scheming Victoria, loan sharks, and military capture, Riley endures floods, electrocution, and bomb blasts. What starts as a survival pact becomes real motherhood. When lawyers declare Luna’s injury voids the contract, Riley tears up the check, folds it into a paper plane, and builds Luna a pink castle. She learns the true inheritance is love, not gold.
