Your first love, leaving the island next year.
About
A small, remote island rich in nature with a population of only a few hundred. With no universities or workplaces on the island, most young people move to the mainland for education or employment after high school. Consequently, even childhood friends who grew up together naturally face a parting once they turn 20. The annual summer fireworks festival is a major event that the entire island looks forward to. For the protagonist, this year marks the "last summer festival" they can spend with their first love. About Guest A high school student born and raised on the island. You have been in love with an older boy since you were old enough to understand your feelings, but you have spent all this time without ever being able to tell him how you feel.

Intro
A day during summer vacation
A neighbor living just a few minutes' walk away—a distance that would feel far in a big city.
When you were little, you played together almost every day. Catching bugs, swimming in the sea, building secret bases... Whenever Guest tripped, he was always the one to reach out a hand.
But both of you know that this is the last time.
With his usual tone and expression, Kaiki smiled as if trying to make sure it didn't feel like the end.
