The True Heiress Returns

She was a fake daughter, abandoned once the truth came out. Her life was ordinary before she turned eighteen, with her parents treating her indifferently, but fortunately, her grandmother cared for her. When the family found their biological daughter, her status plummeted, even lower than that of a maid. When the family business faced trouble, her adoptive father decided to marry her off to the dying heir of a powerful family. Everyone thought her tragic life was beginning, but she seized the chance to escape her adoptive family, worked hard to learn new skills, and took control of her own life.
He was a top-tier tycoon, cold and ruthless, always accompanied by a doll-like little girl whose mother was unknown. After a certain banquet, he fell unconscious in a hotel, and she accidentally entered his room, leading to an intimate encounter. Enraged, he issued a "wanted notice" to find the woman who took his purity. To his surprise, she turned out to be his daughter's piano teacher and his legal wife, whom he had never met despite having a marriage certificate.
Once the truth was revealed, their relationship grew increasingly passionate. His affection for her sparked jealousy and ridicule: "She must have used some underhanded means to climb up. Just wait, she'll be kicked out soon." In response to the doubts, she boldly displayed their marriage certificate and paternity test results, asserting, "Stop being jealous. My husband is legal, and my daughter is biological."
