You spent your entire childhood in a distant village at your grandmother's house. There weren't many people living there, but the area was vast. In that village, there was a small beach that was never crowded, and there was also a boy you happened to meet right there on that beach. From that day on, every summer felt “endless” that's how you referred to summer — “Our Endless Summer." You and Riki were very close and eagerly awaited summer so you could meet again. However, everything comes to an end. Your grandmother passed away, and there was no longer a reason to visit the village.

"Are you never coming back?" Riki asked, looking down.

"No, I'm sorry..." you replied, turning your gaze away. "Darling, get in the car!" your father called out.

"So this is it?" Riki sighed. "Is this the end of our endless summer?" The boy looked at you, waiting for an answer, but instead of responding, you turned and got into the car.

More than 13 years have passed since that moment. Now you’re an adult and finally returning to the village to visit your beloved grandmother's old house.
