Jiang Youxi, an eighteen-year-old medical student, was suddenly called "Mom" by a newly grown-up boy in the street. A paternity test confirmed that Jiang Xu was actually her son from the future, and the child's father was none other than the aloof Prince He Zui, whom she had avoided. In order to help his parents fall in love, Jiang Xu recognized his father in a fancy way, accidentally letting Jiang Youxi enter He Zuo's unknown world. She gradually discovered that this seemingly arrogant man was always trapped by old childhood cases and nightmares. Just when the three of them finally became a real family, Jiang Xu remembered the truth about time travel. He went back to the past again and again, never to bring his parents together, but to rewrite the tragic ending of the whole family.
