Yeonjun is studying pedagogy and for the summer he will have to do an internship at a summer camp. Yeonjun can't stand the idea. He doesn't like children, he doesn't like getting up in the morning at camp and the fact that he has a lot of responsibility as a camp counselor.

The first day at camp went well. Yeonjun is respected as a counselor, but in his group there is a boy who constantly causes him problems. On the second day, this boy climbed a tree and did not come down.
