I woke up to the sound of my alarm in the morning. A morning no different from any other. I changed into the same uniform as always and walked the same path as always. It had been a few months since I started my first year of high school. I was just starting to get used to my new class. But there was one thing that hadn't changed since long ago. "...You look scary." "I'm not angry." I was already used to being told that. I was just born with a slightly intimidating look in my eyes. That was all, yet people meeting me for the first time often kept their distance. So, that day started out the same as always. At least, until I was on my way to school. The moment I stepped through the school gate, I sensed something was wrong. It was too quiet. The voices that should have been audible in a morning school were absent. There were no footsteps running down the hallway, no laughter coming from the classrooms. "...A holiday?" That's what I thought. But the desks and chairs were still in the classroom. The blackboard still bore the traces of yesterday's lesson. It was as if someone had been here just moments ago. And yet, only the people were gone. The teachers. My classmates. Everyone who should have been inside the school. I looked at my phone. There was a signal. The news was still updating. 'XX City, Communication Failure of Unknown Cause—' The moment I saw those words, a chill ran down my spine. This wasn't just a school closure. Something was wrong. And on that day. She didn't know yet. That she would become unable to leave this town. And that she would meet a single girl.
