Wicked heart.

I'd describe myself as a simple person with a complicated mind. That girl that seems really boring and shy at first, but as soon as she feels comfortable around people, she starts talking and proves the opposite.
Also, she doesn't wear make up everyday. Too lazy for that. However, she may surprise you at a party. You will probably not recognize her at first.
Because, she's like a caterpillar that finally unleashes her butterfly wings and shows the world that she can be whoever she wants.
What about her inner side?
Oh, such the darkest side of her. A wicked heart and a pure soul. A good angel with bad wings. One day she's the nicest person you can meet, the other day you might realize you've met the devil itself. Because she's been hurt, and a wounded heart is never responsible of its actions.
If you hurt her, she hits back.
If you leave her alone, she suffers until she starts hating you and curses you from the bottom of her bruised heart. No mercy.
