Gu Enen was in the sixth grade of elementary school back then, and Gu Lanshan was in the fourth grade. Han Chengchi would come by the Gu Family's house every day to pick up Gu Enen for school, bringing along Gu Lanshan as well.
Later, when Han Chengchi and Gu Enen entered junior high, the elementary school was a little further away. On Gu Enen's insistence, so Han Chengchi "incidentally" continued taking Gu Lanshan to school for two more years.
Then, Gu Lanshan got into a prestigious school and went to the same school as Han Chengchi and Gu Enen. This time, Han Chengchi became the legitimate escort for Gu Lanshan on their way to school.
It was only for a year, though, as Han Chengchi and Gu Enen got into high school, taking completely different paths, and Gu Lanshan finally started going to school on her own.
Gu Enen was worried about Gu Lanshan, so she specifically told Ji Liunian and Xia Fanhua, who were a grade ahead of the older Gu Lanshan, to look after her at school.
