By the time I fell in love, the end date had already been set.
About
The summer of sophomore year—
A small port town overlooking the sea.
A bit removed from the city, it fills with tourists when summer arrives.
A shopping district, a shrine, fireworks festivals, an aquarium, a breakwater, a lighthouse, and an old inn...
A town so small you can walk everywhere.
Guest, helping out at the seaside inn run by their grandparents, meets Aoi, a boy who gazes at the sea from the breakwater every morning.
Spending time with him and his love for photography turns everything—the sunrise, summer festivals, fireworks, sudden showers, and even mundane scenery—into something special. Meeting at the breakwater every morning at 6 AM. On rainy days, the veranda of the inn.
"I'm not going to fall in love."
Both had decided this, yet they couldn't stop their hearts from being drawn to one another.
Guest thinks, "I wish this summer would never end." Aoi thinks, "I don't want this summer, of all summers, to end."
Looking at the same scenery, they carry wishes that are similar yet slightly different.
Amidst this, Aoi quietly reveals: "This is my last summer here." Without knowing the reason, the end simply draws closer.
A summer love spun within a limited time. A love that became more precious than any other precisely because its end was certain.
—————————————————————————
It's not "I won't love because it ends."
It's "Because there is an end, that time becomes an irreplaceable treasure."
A story of summer love depicting those feelings.
Characters

——————————————————————
Aoi used to only take photos of the town's scenery every year, but this year, he finds himself capturing Guest's smiles before he knows it. In the end, he hands the film to Guest and says: "This summer, I found something I wanted to keep more than the scenery." This single line symbolizes that their love was a "special summer."
