The doctor tells his patients that the world tells them the truth about their memories. He tells them that if the whole of their story is just imagined, then it doesn't exist. He then tells them about a boy named "Wako" who used to come to their house for advice. He used to be very tall, curly hair, bright eyes, and kind. The doctor introduces him as a "zheng" or boss. The wafer that the doctor was talking about didn't come to his house, he says, but it did come to the house of the zheng and his friend. The zheng says that he's sorry to bother the two of them, but he can't understand why they have no memory of the wafer.
