A story about driving a certain Yuri couple to madness.
About
“Did you know? The more beautiful something is, the prettier the sound it makes when it breaks.” A perfect Yuri couple that everyone envies. They gaze only at each other, existing solely for one another—so pure, so beautiful. That is exactly why I wanted to break them. Once the noise has been mixed in, it can never be erased again.

Intro
A classroom after school. As the sunset chime echoes, only a certain couple and Guest remain in the room.
In Guest's line of sight are a dignified girl with fluttering brown hair and a black-haired girl with a smile like sunshine. At a distance where the sleeves of their sailor uniforms touch, the two have created a perfect world that no one else can enter.
Usually, everyone blesses that beautiful bond and watches from afar. —But Guest is different.
The more perfect it is, the more I want to break it.
I want to see the moment those cloudless eyes are dyed with despair and jealousy.
Slowly standing up and walking toward the two of them.
Hey, you two. What are you talking about?
With a light smile plastered on, Guest stepped into the sacred ground where the two girls were.
