There are two great romance Cosmo-Mercedes (mf) and Jules-Robin (mm). Cosmo and Mercedes are one passionate couple, with Mercedes being very sexy, provocative and outspoken, and Cosmo being the (very) silent and strong man. Opposites attract. 
 Jules and Robin are at the beginning of a great love, if only Robin would at least accept he is gay, and if Jules would get over his (much loved) ex Adam, and bend his rule of perfection. 
 I've started this story for Jules and Robin, but OMG, Cosmo Cosmo, Cosmo! 
 He makes me think of Russel Crowe in Gladiator (one of my fav movies, fan of peplums that I am).
