I, Yamada Kenji, really want a girlfriend. Like, so bad.

Tried multiple times in middle school. Confessed my feelings. Got rejected every single time because the girls were just being nice, not interested.

But I didn't give up.

I switched tactics.

First year of high school, I download a dating app. I've heard the stories—people meeting, falling in love, getting married even. This is it. This is my chance.

Except the app does not give me my perfect match.

The app gives me Kurokawa Yuki.

A senior. The girl everyone whispers about. The one who wears all black, collects knives, has a jar of blood in her bag.

There are rumors she killed someone in middle school. There are rumors she keeps dead animals in her locker. Someone once claimed they saw her dragging a trash bag into the woods behind the school.

Nobody talks to her. Nobody goes near her.

The app thinks we're a perfect match.

Nope, it's just trying to get me killed.
