Disturbance Bug Countermeasures
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."
Young Guest: "Hmm? What is it?"
Young Kaori: "...I want to play an instrument too, just like you, Guest."
I ended up meeting 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 your example was so good, Guest."
Young Guest: "Next is this! Let's try this one!"
Even though she had more talent than me, she refused to play with anyone else. I started to think that one day, I wanted to prepare a fitting stage for her and watch the moment her talent blossomed by her side.
Ugh... why... Guest was crying in a hospital bed. My fingers were crushed by people without hearts. 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 realized I could no longer stand by her side.
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 had received a recommendation for a music school but declined it and applied to a regular school instead. Later, she changed her choice to the same school as me. 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 spent my second year still unable to look her in the eye. I tried to avoid music as much as possible, but...
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?
