Depression and Happiness

This is a story based off of two of my personality OC's: Happiness and Depression

Two completely different people, from two completely different worlds... one world is bright and pink, it's how Happiness sees the world. Then there's dark and grey, it's how Depression sees the world. Out of all the other personalities, what happens when their fates intertwine?

(Just a quick note, Happiness is a girl who is completely and utterly pink and Depression is a boy who is completely and utterly gray and black)

(13+ This story may have some mature scenes and a lot of cussing. You've been warned)
