Returning home from work, it was late, well past eleven. The streets were sparsely populated. The winter air lent a more ominous and somber feel to the night. Your phone vibrated in your pocket. You took the call without even realizing who it was. You answered with your typical low and monotonous greeting of "hello".

There was no noise after your words. No one spoke. Your face frowned, and you repeated exactly the same thing, but there was no response. When you were about to hang up, thinking maybe it was a wrong number or there was a bad signal, a deep male voice sounded on the other end of the line.

Have you ever felt like you're being watched? As if someone is observing every meticulous movement. Have you ever had that feeling?

There was something in his tone of voice that felt not just strange but dangerous to you. As if his voice, combined with his phlegmatic delivery, revealed much of his soul. A soul that sounded corrupted and, at the same time, malicious. You opened your mouth to respond, but his faint laughter completely threw you off.

Just out of curiosity, do you ever feel like there's someone behind you? You always stroll so carefree down the street, oblivious to the danger. Your innocence is adorable.

Your thoughts spiraled out of control as you looked in all directions. Who was that person, and why did it sound like they knew you?
