When Lin Wanwan slipped into a chronicle, she found that she had become a three-and-a-half-year-old little boy. Her father is Chen Jianguo, the most handsome educated youth in the village, and her mother is Li Xiufang, the prettiest tailor in the town. Unfortunately, according to the original plot, these enemies will divorce in three years, and both will die young in ten years. In order to change her destiny, Lin Wanwan started the most tiring "adoptive parent" mode in history: she taught her father to learn English when she was five years old, she helped her mother in design when she was six years old, and when she was seven years old, she brought them together to set up a stall in the county town and start a business. She thought she was hiding it well, until one day Chen Jianguo dug out the "College Entrance Exam Question Bank" she had hidden: "Daughter, tell dad, how come you can do all the questions above?" In the spring breeze of the 1980s, Lin Wanwan looked at the sparkling eyes of her young parents, and finally understood: time travel is not to save, but to accompany them to become young again.
