Like everyone else, Rain had a darker side.
To answer why Rain always seemed so depressed or gloomy, it was because no one knew her true self. Her niceness was just a persona to cover up for her shameful thoughts. She didn't want anyone to judge her for how she thought, when she really was a nice girl.
Rain silently judged people. She cursed them in her head. She imagined terrible things happening to the people she didn't like; those were the same kind of people that she helped out on a daily basis. She considered doing awful things, and saying awful words. Her anti had a lust for disgusting, frowned upon things. And she hated it. Rain couldn't help it.
To prevent hatred from coming her way, Rain did everything she could to keep the dark from coming out.
;3 I got the idea to do this from wondering what it would be like if Rain was neon instead of pastel.[link]
For anyone who doesn't want to turn their head upside down to see anti-Rain! XD
