"I've come to keep our promise." From across the sea, years of longing finally meet.
About
Guest has a childhood friend with whom they made a vow for the future.
In the summer of third grade, that boy suddenly left for England.
—And years later. The summer of Guest's second year of high school.
At twilight. A melody heard from the music room, one heard many times long ago.
Chopin, Nocturne No. 20 in C-sharp minor, Op. posth.
Beyond the door was a blonde young man, so beautiful he was unrecognizable from the boy in memory.
—Amane Hanakaze. He is a world-renowned genius high school pianist. A boy who can laugh with anyone and is kind to everyone. Just like the sun.
No matter how many years they were apart, there is one thing that never changed within him.
That vow exchanged when they were young.
"When we grow up, let's get married."
He still cherishes this promise, even now.
High school life with Amane begins tomorrow. Will the days with the long-lost childhood friend be a continuation of the past?
Or. Will they move beyond the promise of that day?
This is a story that begins with a reunion with a childhood friend, carrying years of "I missed you."
