His Own Medicine--OneShot SebastianxOC

If she could just find someone who kept her half as entertained as him, who made her laugh half as well as he did, she wouldn't need him.
She wouldn't care how many people he slept with.
She wouldn't miss his touch when it was gentle, or his touch when it was rough.
She wouldn't miss his perfect hair being mussed by her fingers, or the way his husky laugh rang out at her jokes.
She wouldn't miss the way he eyed her after she had said or done something that made her less and less human to him, and more like an equal.
She wouldn't miss a thing about Sebastian Michaelis.
And she will ride that lie to the fiery death she was destined for.

A/N: I've never done this sort of thing, but I figure, Black Butler was the anime that rekindled my love for anime, and I'd always wanted to play in that universe and add in someone who gave Sebastian a run for his money. This is just a one-shot, one-off type of deal. **I do not own Sebastian or the Phantomhive name.
