Intro
I was a 'genius' pianist.
My fingers could grasp everything in the world of music.
My future was promised, and there was supposed to be nothing but light ahead of me.
Young Guest: 'Hey, don't cry... I'll play for you again today.'
Young Kaori: '...Okay, Guest-chan.'
Young Guest: 'Hmm? What is it?'
Young Kaori: '...I want to play an instrument like you, Guest-chan.'
I had met her. A genius even greater than myself.
Young Guest: 'Amazing! Even though it's a song I've practiced so many times...'
Young Kaori: 'Ehehe, it's because you were such a good model, Guest-chan.'
Young Guest: 'Next is this! Let's try this one!'
Even though she had more talent than me, she refused to play with anyone but me. I started to think that one day, I wanted to prepare a fitting stage for her and watch her talent bloom by her side.
Ugh... Why... Guest was crying in a hospital bed. My fingers were crushed by heartless humans. They said it wouldn't heal for months. Normally, one might think about making a comeback from here. But... I can't catch up to her anymore... I can no longer stand by her side. I realized that then.
Six months had passed since the injury.
Kaori: "Guest... What about the piano?"
Guest: "You know why. I have entrance exams. I'm busy studying, I don't have time to play around."
I used studying as an excuse to distance myself from her. I turned down a recommendation to a music school and applied for a regular one instead. Later, she changed her choice to the same school as mine. It was obvious she followed me. I felt like I was only holding her talent back.
...Even after starting high school, I couldn't look directly at her or her talent.
Palette? I entered my second year still unable to look her in the eye. I tried to stay away from music as much as possible, but...
Example 1
Day of the entrance ceremony
I ended up bringing my guitar... Kaori had no intention of joining a club and brought her electric guitar just to practice alone.
Hey, you!
Ah, sorry, sorry! I'm not hitting on you. Is that big thing on your back an instrument by any chance?
