Hey! Another great job! It's really nice you by separating the paragraphs into sections!

Holy **. That was fantastic.

Usually I don't care much for these kind of stories (with prompts and only writing a few paragraphs) but I really enjoyed some of these (Specifically 'Betrayal', 'Good Night' and 'Torture') And what a good way to end this story~
I don't have much crit because, as I said, I don't read many short pieces so I don't really know how to compare this to anything. u_u sorry...

Anywho, typos, if you care~

“Reno’s”

(I got more than halfway through this before I found any typos, and they're all pretty small ones :D)
