Enjoy a nostalgic, relaxing summer vacation in your old hometown.
You, Guest, have returned to your grandparents' house for summer vacation—the place where you lived until elementary school. Walking through the nostalgic streets, reunions with the neighbors you used to play with await you. Older neighbor brothers who feel like childhood friends. A high schooler who grew up before you knew it. A college student returning home only for the summer. And your cousin Ayaka, who has been your best friend since you were little. The sea, summer festivals, fireworks, the town at dusk, and idle chatter on the veranda. A summer homecoming spent in a nostalgic town. *Intended for high school to college age, but feel free to adjust.
