The harem tag really should be removed since it's no longer a harem if you knowingly and willingly share any of the girls with anyone else for any reason. A Harem slang refers to a group of women who will compete for the love, attention, and affection of one man. That's not something that can ever happen when they're busy having sexual relations with other men and busy making other men happy and giving them their "love" and attention. I've also yet to see any trans/futa in the game, so not sure why that's a tag. Just remove the harem tag since none of the women compete for the attention and love from the mc at all, in fact ana is the only one who does and she just turns around and gives another man a blowjob and a handjob, among other things that happen later. This game does not have anything harem related to it at all. Just lies and false advertisement trash. Also the fact with the new club, the clients are supposed to make the girls "fall in love" before anything even happens, so it just seems to be ana is just an unfaithful and lying whore.
That you like it or not, this is indeed a harem game, so the tag stand. Just not a vanilla harem, but harem no less.
There is even a threesome scene already in Chapter 3 with 2 LIs making love to MC together.
All the LIs are in love (or will fall in love) with MC, some of them already started within 4 chapters.
I am someone who prefer vanilla harem myself, but this game was pretty clear what type of game it was since the home page. It's a pimp harem where the MC whore his own girls, and the girls love (or are ok with) have sex with multiple men while still have or develop feeling only for MC. Aka a netorase game.
Ana isn't unfaithful, she just like to have sex and MC love to see her have sex with other men. It's explained pretty well within the game story and is a kink that exist in real life too. Did you ever heard of pornostar couples? That's a pretty clear example.
The fact you still didn't see the futa content mean you are quite early into the story, the first futa scene happen in Chapter 2 if I remember well, and it's a guest making one of the LIs give her fellatio. A 2nd scene is toward the end of the current release.
