Roman and Noah used to date and broke up right before they started working for Corbin Fisher.
What you might not know is these two used to date, and in fact both landed at CF at the same time because they'd talked about applying together. They split up right around then so were never dating while actually appearing on CF, but the entire time they've each been here things have been building up to this break up sex episode. Mind you, it's not like there's been any anger or hostility between them. They've gotten along with one another just fine, kept in touch, but had never gotten around to Roman fucking the absolute daylights out of Noah as they've each clearly desperately wanted since breaking up until this episode right here.
