The next day at school, the girls try to build a basic bathing room, which will consume 100 stone and 100 wood. The girls decide that they are in a game, and they are not interested in the flatness of the body. They are interested only in the fact that they will have to eat pancakes for breakfast the next day. When the girls realize that they have done something self-destructive, they rush out to wash up. They realize that it is chen who has done the deed, but they are ashamed and vow never to do it again.
