Price
It's an old saying that "everyone has a price" but he can't seem to find the tag. They say clichés are based in truth, but everybody lies and people are fallible. Therefore, he figures that the more people there are who agree on something, the less likely it is to be true, because what he wants is not for sale. He has enough money and power to buy himself the rest of the universe (the conquest is just for fun. He knows how important it is to Red that they prove they deserve the power, so he goes along with it), but he cannot afford the one thing he desires most of all. Affection cannot be purchased; a heart cannot be sold. The cost of making his affections known is too much to risk, and he could not bear to lose what closeness they share within the boundaries of friendship. It's not what he wants but it's the most he can have, and he will offer however much Red asks. Somewhere, though, in the back of his mind, Purple waits patiently counting pennies in a jar, praying one day he will earn enough to own Red's heart.
A/N: I'm seriously sorry for the lack of updates... my personal life has been an absolute mess. It's been a story in itself. If anybody has a request or a prompt or something, feel free to send them my way; I'm more likely to write if it's for someone else than myself.
Thanks so much for sticking with me, all of you following this. You make it worth writing.
