When The Devil Knocks

Every year on midnight of my birthday, someone knocks on the door. Every year I open the door to check only, to to find noone.
Tonight was my 20th birthday.
Tonight the know happened again.
Tonight I opened the door again.
But tonight there was someone.
A stranger from my nightmare last night. A string magic wielder who saved me from a being in my nightmare.
But what I didn't know that the man infront of me eat the devil itself.

My life was about to take a drastic turn. Will it be for the good or for the worst?
Only the future can tell.
