Three years ago, a well-designed misunderstanding caused Su Wan to flee from the arrogant Lu family CEO Lu Chengxiao with her unborn child. She took root in Jiangcheng, a small town in the south of the Yangtze River, and became an independent illustrator. She raised her son Su Nian'an to be well-behaved and sensible. She thought such peaceful days would last forever, but an unexpected reunion broke all the peace. When Lu Chengxiao saw Su Nian'an, who looked very similar to him, he was instantly overwhelmed by dusty memories and surging regret. The former aloof CEO lowered his status and clumsily learned to be a qualified father while trying his best to recover the love in his heart. But obstacles came one after another, including the Lu family's family background and the obstruction of the person who caused the misunderstanding. Su Wan is struggling with the pain of the past and her son's longing for father's love. Can Lu Chengxiao resolve everything with sincerity and make this family of three truly a complete family?
