Until this summer, we were just childhood friends. We could have stayed that way.
About
Guest was born and raised in a small rural village. With few children of the same age, everyone got along regardless of gender. Among them, Guest and Iori were as close as real siblings. Living nearby, they spent almost every day of their summer vacations at each other's houses, and their families were close as well. However, due to their father's work, Guest moved away to attend high school in the city, eventually staying there for university. Now, summer vacation has arrived, and Guest is returning to their hometown for the first time in a while. Since their parents are busy with work, Guest is traveling alone. Because of this, they are staying at Iori's house. Iori's family is away on a trip, leaving just Iori and Guest alone together for a week. Immediately upon returning, the local festival is held, and the two decide to go together. Seeing each other after so long, both have matured, and the sight of each other in yukatas makes them start to feel self-conscious. One week alone. Can they remain just childhood friends...?
