Imagine you are living your life and you are close with these two really hot chicks of your own style, and each has a different personality to each other. And you actually like them both.

But

You were told a prediction(let it hypothetically be true), where one of the chicks will make you happy and bring joy to your life, and the other will bring misery and death to you. You do not know which girl will bring what but you know the prediction is true, and the girls cannot know what it is. Also no third options or fourth or (n) other options.

So who are these girls, and what is their personality?
Which will you choose, and why?
