The teacher tells the students that they will be going to a sketching location to practice their sketching skills. He tells them that they must wear their school uniforms and not to cause trouble with the local people. He also tells them to sigh at least one time each day to avoid getting lost in the group. The teacher then tells the boys to help the girls pack their luggage and to sigh when they need help. He then explains that sighing is one of two meanings: the first is being at ease and the second is having no alternative. He explains that he saw his male idol hanging out with another student who does not try to help them. The group has been assigned a long bus ride, and the students have to sit in different classes to get to the destination
