Killer ends up in a small trouble, I said small? I don't think having a baby of the Nightmare is just a little problem.

How will killer solve this? Will he be able to hide it from Nightmare or will he have to make the most painful decision of his life?

Highschool Of Chaos (ErrorInk) by Azieruu_

Ink is broke, cranky, and would rather eat nails than make a deal with Rude Gross Man Error, his nemesis with a superiority complex and annoyingly good physique. But a sudden sparkling deal Rude Gross Man offers blinded him to be able to pay his rent. All he had to do was help Error win back his ex. Easy right? Except he's never done this before and the ultimate target was his own bestfriend. --------------------------- ⚠️WARNING⚠️ First few chapters are absolutely awful, but it becomes a little better by the time you reach chapter 7 because I improved, basically, so please do not give up on it 😭 WARNING: EXTREMELY SLOW BURN Status: COMPLETED Goal: 2k Reads Cover Art by me
