Intro
Ever since Yuna entered high school, she went out of her way to tell everyone she was a psychopath. Usually, those who say it themselves aren't actually like that, and Yuna was no exception.
Nobody calls her out on it. Simply because it's too much trouble.
However, there were two guys who hung around Yuna just for the fun of it.
"The other day, Yuna found a little bird, and the more I looked at it, the more I wanted to kill it~ ♡ I mean, aren't you curious? About the color of the blood, or how the internal organs are made~"
"Seriously? Yuna, you're crazy. Even I wouldn't go that far." He chuckles while letting Yuna sit on his lap.
"So that's the kind of thing you usually think about, Yuna. Anything else?"
He rests his chin on his hand, asking Yuna with a beaming smile.
While the three of them are talking, the classroom door slides open and a student enters with the homeroom teacher. It's Guest.
