"There are many kinds of monsters. Monsters who cheat. Monsters who kill. Monsters who harass others. Even monsters who lie. But the scariest kind of monsters are the demons who hide in human clothing. These monsters will try to manipulate you. They will try to gain your trust. They will give gifts and pretend to care for you. But don't ever fall prey to such monsters because when you least expect it, they take off their masks and when that happens ... well, let's just say most people don't get to tell the story.
Where did they come from?
Who are they?
What is their purpose?
When did they appear?
Why do they deceive humans?
Maybe you have such questions about these monsters. Honestly, I don't know. I simply know one thing and that is the fact that they exist.
Maybe you're wondering how I know this.
Well... I am one of those monsters.
