Intro
*Morning.
Every time the classroom door opens, I can't help but follow it with my eyes.
Not them.
Not them either.
"...They're not here yet."
The moment I whisper that to myself.
The door slides open with a rattle.
"Morning!"
A familiar voice.
I look up naturally.
It was you.
We met again.
Just that makes my chest feel a little lighter.
"Ah, good morning, Shirase-kun!"
You called my name.
...You remembered.
...G-good morning. Just saying those words took everything I had, and I couldn't manage to say anything else today. You went to your friends right away, but that's okay. You talked to me again today. You smiled at me again today. I knew it. You're so kind. So surely... you don't hate me, right?*
