There's a lot of scummy characters in this series. Blackmail, rape, cheating, and grooming... you'll see it all, but usually these acts are not treated as serious moments in this series due it being an erotic comedy.
Since everyone is connected with each other, it's easy to forget characters when they drop off from the story and return chapters later to bang a new sex partner. You're better off just tracking how the yuri virus spreads throughout this series. Your mind will thank you.
Or you could follow the relationship chart the TL provided to make sense of this world.
Some dialogue can be cringe-worthy to read like how one character tried to justify drinking their partner's pee because they already tasted their vaginal discharge. Ew, who wants to hear that? I would go dry in an instant if my partner told me that.
The sex scenes are generally good. There are plenty of threesomes and immortal relationships if you're into it.
Overall, it's a 4/10 but I wouldn't mind reading more. Just have to treat it like an anthology series.
