A titular character

She'd found them in a book from the school library.

There was a secret tome, hidden behind the few books about how to make friends, that seemed to guide the user to the ultimate power. It was a long book that the girl had read in full, only to find a gift at the end of its pages.

A set of earrings that could change reality as long as you uttered the word 'normal' when you wore them.

Anything was possible. Limits were removed. All your dreams could come true, all had to do was say that word.

...

"I-i-i-it-ttt's n- n- n- n- n- n- n- n- n- n- n- n-"

................

Komi wants to say 'It's normal for everyone to be my friend.'

She wants to say 'It's normal for me to be able to speak like a regular person.'

Even the more perverted nature of this timid girl was screaming out for her to say 'It's normal for Tadano to be my boyfriend and hold my hand.'

But she didn't say any of that.

Because Komi Shouko has a communication disorder.

So she took the earrings off and put them back where she found them.

April fool.
