Genius programmer Yu Ning was accidentally reborn as a three-and-a-half-year-old dumpling named Yu Nuannuan, and was bound to an unreliable system "Fufu" that was always crashing. He has an adult mind but is limited by the warmth of a child's body. He uses childlike words and super cute actions to heal the knots of everyone in the Yu family: allowing the workaholic father to regain the warmth of family, helping the elder brother with social phobia overcome his fear of speaking, rekindling hope in life for the depressed mother, and even allowing the rebellious second brother to take the initiative to learn. In the kindergarten, Nuannuan solves the children's conflicts in an unconventional way and becomes the favorite of the whole kindergarten. And the system that always said it was about to release tasks but always crashed was finally discovered to be the heartwarming accident...
