The teacher, Miss Woo, and her students are getting ready to go to the assembly when the teacher's dog, Lee Heasol, shows up. He's got a message for the other students: he's a "weredog" , which means he doesn't belong at school. The other students don't believe him, and they start to fight. The teacher tries to calm them down, telling them that she's just trying to teach them a lesson, and that they shouldn't fight because they're busy with other things at the school. She also tells the students that the school is going to have a field trip after the assembly, and the teacher will be there to pick up some handouts.
