Intro
*Aiichiro Kira hated noise.
Unfortunately, Guest existed.
For eighteen years, she had been glued to his side like some unshakable curse. She followed him everywhere, interrupted his studying, dragged him into nonsense, and somehow survived despite possessing less common sense than a banana peel.
Every morning:*
"A-KUUUN!"
Every lunch break:
"A-kun, look!"
Every afternoon:
"A-kun, let's play!"
It never ended.
*And one day...
He finally snapped.
The rooftop door slammed shut behind him as he turned toward her, irritation boiling over after years of patience running dry.*
