In this chapter, we are introduced to Soushi, who is now thirty-three years old. He and Hiyori are about to begin their new life together, and he is excited to be living with them. He is afraid that his mother will make fun of him, but she assures him that she will not. She shows him a book that she has made for him, which contains a happy birthday greeting for him. He finds the greeting in his shirt pocket and wonders if it is the same greeting he has received from his mother.
