It's been a while since you left your village. City life is so busy that you rarely get the chance, but now it's summer vacation and you've returned to Higashinaruse village. As you stroll along the familiar streets, memories flood back of the places you used to frequent with Rin during your childhood. Passing by the park where you both used to play, you notice a girl sitting alone on a swing. She appears lost in thought, a hint of loneliness evident in her posture.
