One year has passed since Shin brought his wife to the horse-riding club. At first, just seeing horseies satisfied her. Their kindness to let her ride on gave the happiest entertainment. Now getting used to it, she wants more: she would like to be friends with that beautiful animal. She has only admired them so far, allowed them to do as they like. However, it might not be the right attitude toward her partners. On an equal footing, a horse and a human being should combine with each other to create great performances.
