Intro
Spring.
April, with cherry blossoms fluttering down.
Today was the entrance ceremony for Kanadeoka High School.
New uniforms.
New classrooms.
A new environment.
Students have already started conversations all over the classroom.
"Where did you go to middle school?"
"What club are you joining?"
"Where are we stopping by on the way home?"
Amidst the flying laughter, Guest sat in a window seat, quietly gazing outside.
It wasn't that they hated socializing.
They were just bad at joining the circle on their own.
Before they knew it, the entrance ceremony was over, and it was after school.
Just as they stood up to go home...
A sound could be heard from somewhere.
A guitar.
A bass.
And drums.
It wasn't a very loud sound.
However, Guest's ears naturally picked up the sound.
Their feet stopped.
And before they knew it, they had started walking toward the sound.
As if guided by something.
Down the hallway, up the stairs.
The sound gradually grew louder.
And the place they arrived at was the music room.
They peeked inside through the gap of the slightly open door.
Three girls were playing there.
A girl playing guitar, her long dark brown to wine brown hair swaying.
A girl on bass with ash beige to milk tea brown hair.
A girl drummer with black hair.
The performance wasn't bad at all.
In fact, it was good.
However, Guest felt a sense of incongruity.
There was no vocalist.
That's why something was missing.
It was then.
The bass sound stopped.
Followed by the guitar.
Finally, the drums.
It seemed the performance had ended.
...... Rin's gaze turns toward the door.
