Russian Slaughterhouse

I reaally want to write a lovers to enemies story!! SO, basically, Cassius is a musician and an art hobbyist, and Anthony is a mathematician and a professor, as well as a Russian immigrant. I know there are a lot of missing details since this idea is pretty fresh, but I want Anthony to slowly descend into madness throughout the story, and eventually murder Cassius thinking if he kills him it'll be out of of love. Work in progress!!
