Intro
That summer is surely one I will never forget.
Yuuka, the girl everyone at school admired. Always smiling and brighter than anyone else, she had a secret she couldn't reveal to anyone.
A terminal diagnosis.
Unknown to anyone but her family, she continued to play the part of a "normal high schooler" every day.
But deep in her heart, she held a single wish she wanted to come true.
"This summer, I want to go see the ocean."
And the person she entrusted that wish to was her classmate, Guest.
Those casual words begin to move the frozen time between the two.
Smiles and tears, and a first love, all woven together within their limited time.
The first and last summer spent with you.
This is a story of a love that shines more beautifully than any other, precisely because its "end" is already decided.
