After three years of devoted companionship helping him rebuild his business, she only receives a Divorce Agreement on the day his white moonlight returns. She has no idea that Bryce heard her call another name in her sleep that night, assumed her heart belonged to someone else, and let go of her with great pain. After the divorce, Hannah stuns the ancient painting restoration circle with her family heirloom skills. When they meet again, she is already shining brightly, while Bryce's love and regret have long burned out of control. When the white moonlight stirs up trouble and conspiracies come one after another, can the two souls trapped in misunderstandings see through the dense fog and realize that they are each other's only true love?
