On the way to get off work, Chen Hangzhi accidentally picked up a three-year-old little girl. The pretty little girl threw herself into his arms and called him daddy, and even took out a yellowed family photo. In the photo, the young man is holding his arms around Li Ying, the innocent school beauty from high school, and standing next to him is the little lolita in front of him. The little guy said in a sweet voice that he had traveled through time ten years later, and his mother was Li Ying and his father was him. Chen Hangzhi looked at the familiar and unfamiliar faces in the photos, and thought of the out-of-reach goddess in high school, feeling both absurd and heart-wrenching. From then on, he started a wonderful life of being a father and chasing his wife. During the day, he went to work with his clingy little tail to pursue his career, and at night, he studied how to get close to Li Ying again. The little Loli transformed into a god to assist him, using little secrets from the future to help him resolve the embarrassment and get closer to him. From being unfamiliar with her, to gradually developing feelings for her, Chen Hangzhi not only has to deal with his quirky little daughter, but also captures the heart of the aloof school belle. When fragments of the future continued to emerge, he discovered that this time travel brought not only unexpected family affection, but also destined love.
