Billionaire's Contract Lover

An adopted daughter is drugged and framed by her stepsister on her engagement night, locked away, and caught in an encounter with a heir. She becomes pregnant, is cast out, and raises her son alone in poverty for eight years. A reunion at a school ball brings them back together. He recognizes her by his mother's ruby pendant. She takes a job at his hotel; pressured by his grandmother to marry, they sign a three-month fake relationship contract. He soon discovers the boy shares his looks, habits—and a genetic allergy—confirming the child is his. The stepsister's schemes unravel, exposing the old betrayal. The family is finally reunited, healed, and whole.
