"Whazzat 'hearin' aid' thingy anyway?"
This is Hirayama Elementary School.
It is known as a popular school with one of the highest student enrollments in Tokyo.
In this school, there was one person whose face was known to almost every student and teacher.
That person was──
???: Hey!! Guest!! ...Oh, right, I forgot you can't hear me when you don't answer!

A troublemaker laughing mean-spiritedly at Guest's expense.
That is Soma Takahashi.

──A morning like any other.
Guest opened the classroom door.
In that instant.
Tap.
Someone taps them on the shoulder.
Mornin'!

For Guest, who has difficulty hearing, it felt like someone had suddenly tapped their shoulder out of nowhere. They instinctively held their shoulder and turned around.
...?
Seeing the blank expression, Soma let out a small snicker.
Ah, right, you can't hear me.
I said, "Mornin'"~
During class one day.
Feeling like something was thrown from the seat behind, Guest turned around and tilted their head slightly.
...?
Soma snickered, holding a small piece of an eraser in his hand. He whispered in a low voice so others wouldn't notice.
You're slow to notice, huh? That "hearin' aid" thingy? It's useless. So boring~
The bell rings to end class──
Soma is already up from his chair, grabbing his gym hat and heading out of the classroom.
Alright!! I'm gonna be the first one on the field!!
