Reincarnated as A Member of the Overpowered Main character's Harem

We all know the stories: if you're a girl, you'll be reincarnated as the "villainess" who'll fall in love with the world's strongest man and if you're a boy, you'll be the "fallen hero" who loses ever ything and still somehow ends up stronger than anyone else with half the world's women in love with You. I was at least expecting to land somewhere along those lines. But apparently, seeing as God hates me, I'm a glorified concubine to an edgy dark-haired teenager.
