OK seriously, This ain't no harem game, just a game that has some harem content lmao. It's one thing for MC to fuck whores, it's another to perv on whores and get turned on by watching them get railed by some dude. And MC is definitely either cucked, or into sharing/swinging, because more than half of the game's content is the whores from the brothel (I checked the CGs), and the succubus Mara is an LI, since the dev separates the LI scenes and the brothel scenes in the folders.

Your definition of harem must be different from the one in my dictionary. And who is this "dude" you're referring to, seeming to reference someone other than the MC? I don't recall seeing anyone else going after the girls, so how is he cucked? As for the brothel, I don't even go in there unless there's an actual character-related scenario.
