Well just for reference on your part, here is the setting of the rp and past of the character I want to play.

Basically its a world where robots have taken over everything and want to get rid of all the humans. The more dangerous humans they just kill, but some that have useful skills or are less harmless the robots change them, turning them into Androids. The humans' bones, and eyes are replaced by mechanics and a chip implanted into their minds, making it seem like they are machines, turning them essentially into half robots, though you couldn't look at them and tell physically because they look the same as they had been human. The only difference you will find between this Androids and normal humans that you can physically see is that the Androids have a bar-code tattooed onto their arm(underneath the tattoo is a tracking chip as well). Any humans still alive and not changed by the robots are living in hiding away from the robots, having to scavenge for supplies, food, ect. 

My idea for the rp would be that I would play a girl who had been captured on one of the humans raids for finding supplies and turned into an Android. Androids are to supposed to have any memories at all of their previous life(the chip in their brain on top of increasing their intelligence and react times, ect, also blocking the previous human memories), but the girl has been having flashes of memories. Not much, just images of certain things. This makes her more and more less willing to do the robots bidding and soon she runs away from the robots, where she manages to travel by instinct to where she had lived as a human(though she doesn't remember she did); the human resistance hideaway hidden in a cave in a dessert. The moment she enters though, the humans capture her, about to kill her, when someone stops them. A young man(who you would play), whom when she was human was her fiance. They proceed to try and convince him she's not the same and that she doesn't even know who he is(which is technically true, her only having seen quick images of him left over from her human memories seeping through), but he refuses to listen to them. Finally coming to a decision, they decide to not kill her, but keep her prisoner there in the caves until they can figure out what to do with her. You could take this character in many ways such as him being gentle and trying to coax her to remember, or he could be somewhat angry toward her now that she is an Android. How you want to play him would be up to you.
