It's a game about lesbian and queer romance and swordplay
It's a hit among the LGBTQ+ crowd, and specifically the lesbian, trans, and queer audience members
For context, when it comes to lesbian and queer romance, the 'sex' part of sexuality is pretty minimal compared to everything else. IIRC there's very little in the way of actual sexual content in the rulebook. Au contraire, everything is heavily drenched in mutual consent, positive experience, and, well, the cute-gay-shit side of being gay.
It's not as bad as you're thinking. It's very much in the modern style of powered by the apocalypse games, but instead of investigate then combat, it's romance then combat. It's, perhaps obviously targeted at the LGBTQ community, and that shines through in the art and mechanics, with non LGBTQ relationships being almost an after thought.
If I had to describe it as simply as possible, I would probably tell you to watch She-ra and the princesses of power.
