It's time to clean up the playground, and Mr. Cang is eager to get back to work. He coughs and complains that he's been poisoned by the alien food. The teacher explains that it's not uncommon for people to get sick from eating alien food, but that this kind of food is very rare and only a few people have ever gotten sick from it. He also explains that the person who gets sick from the food has to swallow a lot of it, and that's why it hurts so much. He's waiting for him, and when he finally gets there, he tells the teacher that he just had a "weird dream" in which he saw a silver-haired boy. The boy is crying, and the teacher is happy that he had such a dream.
