Su Ruotong works part-time as a designated driver. She reads novels and plays sign-in games, only to have her soul drift into a parallel world in the 1970s. The lack of food and clothes is bad enough, but she has also been reborn in the body of a three-and-a-half-year-old girl.

At an age when she's only just learned to use the toilet by herself, what can she possibly do? The only thing she can do is try every way she can to stop her stepmother and scumbag father during those few days.

With the help of her sign-in System, she feeds her scumbag father and stepmother pills that render them permanently infertile, solving the problem once and for all.

Her scumbag father uses the excuse of looking after the original owner to marry his new wife.

He entrusts his new wife with the inheritance and compensation money left by the original owner's birth mother.

Her stepmother even wants her to do the laundry and cook. She agrees, then turns around and goes to Grandma Wang, the head of the publicity team, to cry about how wicked her stepmother is before reporting her to the political commissar.

She finds herself a powerful military officer to rely on. The Living Yama washes her face, combs her hair, and ties it into little pigtails. He also stands up for her and helps her get even... When he goes on a mission, he leaves his younger brother in charge of looking after her.

The younger brother takes even better care of Su Ruotong than the Living Yama does. He's a pro at laundry, cooking, combing her hair, and tying her pigtails. He also flies kites and sings nursery rhymes.
