Ever since Yin Yang left, Xu Mumu has been taking the little one everywhere to play, even visiting Professor Song's classroom twice during their lectures.
While she enjoys going out every day, she wishes she could spend more time in the lab, but the little one is still too young, and she doesn't trust leaving the child with others.
Watching the children at home preparing for the high school exams, working hard each day, Xu Mumu brings Doudou over not just to cheer for them, but also to impart some of her own experiences.
Even though they've done many exercises, with piles of papers stacked high.
But it's the high school exams; they don't dare get careless. The teacher has shared many examples of students who were top performers but didn't do well during exams; they don't want to make mistakes during the high school exams.
