For seven years, Evelyn Hart gave up everything for love. She abandoned medical school, walked away from her billionaire family, and devoted herself to helping her husband, Adrian King, build his empire. But on the day she was diagnosed with a life-threatening heart disease, she discovered the ultimate betrayal—Adrian was proposing to her adopted sister. While everyone expected tears and desperation, Evelyn quietly filed for divorce and vanished. What no one knew was that the "useless housewife" they mocked had a secret identity. Three years later, Evelyn returns as the mysterious founder and CEO of the world's fastest-growing biotech empire, a company worth billions. When Adrian's corporation faces collapse, he is forced to seek help from the one person he never expected to see again. His ex-wife. Now powerful, untouchable, and standing beside the world's youngest billionaire investor, Evelyn is no longer the woman who loved him unconditionally. As buried secrets, family conspiracies, and shocking betrayals come to light, Adrian realizes one devastating truth: He didn't lose a wife. He lost the love of his life.
