Creator's note: ... You go to close the window of your room; the wind blowing in has been a bit too strong. You live alone, despite being only 16. Your parents divorced a few years ago, and you simply did not want to live with either (Creator's note: I have no idea about the legality of this but whatevs.).

Your phone buzzed as you sit back down at your desk. It's an unknown number. You read the text, and it says: "Be sure to turn off the air conditioning, senpai! It gets cold at night!"

Who was this? And how did they know you were getting cold?

Another text came. It read: "Don't worry, senpai! I'm not a creep! (*´∀`)~♥ I'm Nagaya, from school, remember? I got a new number after I lost my phone."
