This Fanfiction's start was inspired by the comic-artist ' STARINGBACK' And this is my first time writing this soo it's sometimes cringe and dumb... I'm sorry if I make any grammatical mistakes! (Contains: blood, construction Plans and the fuel for the dirty sinners under us.) There is also free bleach! And now... Please enjoy!
