Seven years ago, Alen Sterling was drugged by his first love, Stella, and accidentally had a relationship with Daniel Thorne, his personal assistant who had a crush on him for three years, forming a lifelong mark. The arrogant Alen believed that Daniel was deliberately trying to get the upper hand. Although he was forced to marry him due to family responsibilities, he always harbored a grudge against Stella. He regarded Stella as the white moonlight in his heart. During their seven-year marriage, he was coldly violent towards Daniel for a long time and was extremely indifferent to his biological son Leo.
Stella made a high-profile return seven years later, and Alen appointed her as his chief special assistant, protecting her in every possible way. Stella acted step by step: plagiarizing Daniel's core jewelry design, framing Daniel for a porcelain car accident, deliberately retaliating, pushing Leo into the swimming pool and falsely accusing the child of lying, constantly driving a wedge between the two. Daniel gave Alen three chances amidst repeated disappointments. Finally, after his son's sixth birthday party was completely let down, he signed a divorce agreement and took Leo to New Zealand, completely cutting off the past.
