What happened to my sister and brother after school?

The story of my sister and brother playing after school comes from videos posted by some blogs in Tik Tok. Some bloggers will take pictures of siblings or brothers who play together after school, make videos and send them online. These videos usually contain some interesting dialogues or interactions, such as the scene that a younger brother will be jealous when he sees other children holding his father's hand, or that a younger sister takes care of his younger brother.

After these videos became popular on the Internet, the elder sister and younger brother who played after school became a popular online term, which was used to describe the scene where brothers and sisters played together and took care of each other after school. Sometimes it is also used to express concern for family relations and desire for family affection.
