Su Wan and Shen Yu were separated for five years due to a misunderstanding. As a divorce lawyer, she had just helped a domestic violence victim win a lawsuit when she was retaliated by the murderer and died tragically in a foreign land late at night, leaving behind her four-year-old daughter Nian Nian and her adoptive father who was seriously ill. Shen Yu always believed that the child was not his own, and was extremely indifferent to the news of Su Wan's death. It was not until he found out all the truth that he realized that he had pushed away his beloved with his own hands, and lived in irreparable regret for the rest of his life until he died alone.
