Ever since that incident, Gu Xiaobao started caring more about Gu Xiaobei.
He started attending the class for the older age group in the kindergarten and there were more things to learn. His younger sister was slowly growing up as well.
Gu Xiaobei started growing up into a more likable baby and started crawling around more quickly.
As she got older, Gu Qingjiu could no longer stay home to take care of the siblings.
Since she had her assignments, she left Gu Xiaobei to both Hilda and Gu Xiaobao.
Although Gu Xiaobao was a child too, he loved and cared for his younger sister.
