For reason of easiness, I'm going to call them Henry and Ewan. You may name whatever you would like. For the most part, their histories after childhood - teenage years are up to you. I REQUIRE THEIR RELATIONSHIP IN THE HISTORIES. Races are up to you.
"Henry" and "Ewan" go way back. They were once childhood friends that become overly competitive with each other. Both Boys were born in North Shield, England close to the coast. "Henry's" family were fisherman and "Ewan's" family were a businessman. They attended the same early schools and started as friends but as they grew older their competitive spirit against each other grew from sports, to dates. and even career choices. "Ewan" was going to be a better businessman than his father and made the choice to developed technologies. Henry didn't pick business, he choose something more humble that would help more people. Henry became a search and rescue professional.

Eventually, both boys would move to New York to prove they could make it in a different world from their more humble beginnings. Henry would hear of Jupiter from werecat down south. There was no word that he had to look for her or whatever.

Once, Jupiter and Henry started to spend time together, Ewan took noticed. A beautiful little faeling, sweet and pure would do a lot for him. it would polish his image, her abilities gave him business ideas, and it would piss off Henry to end. Ewan was always different. Life was a chess game to him. Ewan waited for a break up, and swooped in like a knight in shining armor to rescue the faeling. A pattern would grow. Jupiter declared herself and belong to neither at one point, knowing she had a long enough life ahead of her, she didn't have to choose until she was damn ready and well aware enough that she and Henry were Rogue and Remy. Off and on like changing of the tides. Ewan proved to be more stable.

PLEASE TAKE INTO ACCOUNT Jupiter cannot have children. If you want children, each character should be old enough to have has children with other people. Plus baby mammas are grand for added drama.

NOT EXCLUSIVE Neither of them are currently exclusive with Jupiter. Probably at this point in time she's fucking both of them.
