I don't want to say too much, to preserve the surprise of the next updates. But the name of the game is not chosen at random. There will, of course, be a system that emphasizes the "pimp" side of the hero.
This does not mean that the game is not categorifiable as a harem.
It might seem a bit crazy to label a game with the "harem" genre and the "prostitution" genre, since players rarely like their favourite girl to end up with a character other than their own.
On that side, I ask you to trust the developer; Me :)
