Yeah, I've just marathoned to 177, and basically they are all as bad as each other and they are all just sleeping with everyone there is. FMC is just using her body to get info on her sister while the MC is just dipping anything on offer. I don't have empathy for any of them. Plus the sex is so generic. They all just keep doing the exact same vanilla stuff.
Plus there are new girls, and even though they are all in danger, they keep coming back for more. I am just skimming it now 😁
