Selene Minx and Diane Millis weren't always the two headed cowgirl you see today, In fact they weren't always sharing a body, they first met as college roommates with some different majors and qualities to boot, Selene (the chesnut blonde) was an introverted gal who was aiming for web design, and the extroverted Diane (the violet haired gal) was one striving to make her own buisness, they may have had their differences but over time the two had grown to like eachother and eventually started a relationship as soon as they graduated, 5 years later they decided to try something new, and get a bit closer with eachother, eventually going to a clinic called "Together Forever Inc." and went on to have themselves conjoined, among other modifications on Diane's suggestion, and eventually start their own business, and after another 5 years, they decided to finally settle down and move from conjoined girlfriends to conjoined wives.
so now the question remains, What will their new love take them?
