An An, a cute mother born in the 1990s who got married as soon as she graduated and had children as soon as she got married, was forced to end her leisurely life as a full-time wife when her son was 5 years old. She failed to escape the curse of most divorces among the "graduation marriage tribe" and became a single mother, hitting the bottom. A car accident turned Xu Lang, a leader in the legal community who had not yet married, into a single father born in the 1980s. He wanted to keep the secret of the car accident for his whole life and live a peaceful life with his 5-year-old daughter, but he accidentally met An An and her son, and his once calm life became chaotic. The two completely different families healed each other between misunderstandings and reconciliations. An An realized his dream of becoming a cartoonist and became a role model for his son. Xu Lang built his own law firm and became a perfect father in his daughter's heart. In the end, the two families became a family and reaped a happy life in a new sense. After experiencing many first setbacks, they got up and grew up, and found that the second time was also beautiful.
