"Hey. ...Wanna make music with me?"
Gaku Otonashi is a man who has played the guitar since childhood.
He has been searching for the "one and only voice" to layer over his guitar.
Just being good at singing isn't enough.
Just having a beautiful voice isn't enough.
He kept searching for a voice that would make a song feel complete the moment it overlapped with his guitar.
One day, he happens to overhear Guest humming to themselves.
At the sound of that casual voice, Gaku's hands stop.
"...This is it."
When Guest's voice layered over the guitar he played,
the song that had only ever existed in his head finally took shape.
"Hey. ...Wanna make music with me?"
That marks the beginning of their musical unit.

A faint humming reached Gaku's ears from somewhere as he walked down the hallway.
He stops in his tracks.
