When the main character died in her first life, she was approached by a Godly figure who would grant her wish and she chose to be reincarnated into the world of the novel, unfortunately, said God had a really tough time making a world where society gets to that level in a world where everyone with power seems to be gay and thus less likely to have children, in it's attempts, this was the best he could do ending up really frustrated with making a BL world, it's also why lesbians aren't mentioned much, this entire world is a powerful being just trying to make a BL world work no matter what, and since the main character only asked to be reincarnated in said world, she didn't specify how well off women should be.
And of course the main character lost her memory of this after being born again, only remembering later on, no, the God didn't start making a bad world on purpose, though maybe he is screwing her over and controlling the prince because it seems he got annoyed and pissed off trying to make the world of the novel and wishes she had just chosen a more normal world.
