Demons and Pills

Demons and Pills.
Ah. A story filled with hidden meanings, poetry, emotions, drinks, contracts, demons and angels alike.
There are clues throughout the story as to what the ending may be. Try and figure out what the ending may be through the comment section. There may be a few mature sections here and there but there will always be a warning.
HINT: This story has something to do with psychology, philosophy and religion.
HINT: Each of the characters are linked with a sin.
HINT: (SPOILER) In a future chapter (this was written on: Tuesday 5th of June, 2018), make sure you pay close attention to a gambling scene. There are some big clues there.

And voila! Three clues to give you a start on where you should go from! I hope I keep you guessing.

I'm sorry if my writing isn't great. This is my first Wattpad story in a very, very long time. Please correct me in places where I have gone wrong ^-^".

Other than that, enjoy!
