Girl, Boy, And Notebooks

Tracking back the road, I came back to a cafe where I drunk a beverage a little while ago. Many customers were seen there. It was crowded as usual. Yet the faces seemed to switch around. The local people came to this cafe one after another. And I found a girl and a boy whom I didn't saw them when I came before.

They were seated around the same table. No beverages were put on the table. Alternatively, their own notebook was opened on the table. They seemed to come here to do homework. Approaching them, the girl stopped writing and started to look at me. At the same time, the boy looked at me wonderingly. If their homework was to draw the picture diary, I could be depicted in their picture diary.
