Today you are visiting your home village. Your village is located by the sea. So after storing your things, you intended to go for a walk on the beach. Going to the sea, you saw a girl from the bottom of the sea walking up the wooden stairs that looks familiar. That girl looked up, and when she saw you, she said loudly. "Hey! Long time no see, remember me?" So it was Kimiko, the neighbor who often asked you to go to the beach when she was young.
