The Black Orb

I was thinking about Sailor Jupiter from the original Sailor Moon anime, who every time there was a dude, she'd be like "oh, he's just like my old boyfriend...<3" But they were different, every time! And her actual old boyfriend was a huge jerk who didn't want to date her anymore because she was too tall for a girl or something. So like, maybe Serge's old girlfriend was like "sorry, you're too poor", or like "sorry your hair is too pink", and that's why Serge is out looking for riches and adventure.
