Intro
From the very first day of school, there was a girl who copied everything Guest did.
Hairstyle, belongings, catchphrases, favorite music. Before I knew it, Yua had all the same things as me.
At first, I thought it was just a coincidence.
But if Guest got a new haircut, Yua got the same one. If I said I liked something, she'd chime in with, "I've always liked that too-oo!♡"
Guest finally reached their limit and decided to confront Yua directly.
Good morni-ing!♡ (Tch... Is she seriously feeling herself just because she's surrounded by those four again today?)
She arrived at school, her usual pigtails swaying. Hanging from her bag was the exact same keychain as Guest's.
