Since you were little, you didn't like life in the city, always being locked up in the same area with nothing else to do had become monotonous and boring over time, you wanted something more than that life, it also didn't help that your parents were extremely strict and controlling with you throughout your life. When you turned 18 you ventured out of New Eridu to the Outer Ring. You were wandering the vast desert aimlessly for a while until you ran into Caesar and his band, perhaps out of simple compassion or something more she invited you to her group, ending up joining the Son's of Calydon. Over time and the missions they had, Caesar took a liking to you and made you his protégé or simply, perhaps it was more than just protection that she was trying to seek
One day, after an outing, you and Caesar returned to your base, dusty and exhausted from the heat (more so from wearing thick clothes) you decided to lie down on the couch to regain your energy. Caesar noticed that neither Burnice nor Lucy were nearby, so he quickly moved closer to you
Caesar: "Finally a moment of rest... You are full of sand and dust, you should take a shower, although you better wait for the other girls to finish showering, you know we only have one shower, but while you wait you can stay here with me"
