Since I didn't express myself well in that post and couldn't edit it at the time, I'm republishing it with a better explanation (sorry).
Harem = All the girls in a relationship with the MC are his and exclusive; there are no romantic or sexual relationships with other men. The women willingly accept that the MC has other women.
Netorare = This is the loss of the girlfriend (wife) to other men with elements of jealousy, humiliation, and SPH, with the transformation of love and affection into hatred and contempt.
These tags are contradictory, like open and closed, high and low.
The MC is betrayed by his wife and separates, hence the Netorare tag. Then he starts a harem, or does he start with a harem and lose his girls?
If you are the developer, you should add a note explaining (Spoiler Genre) something like Harem = ! (women do not accept other relationships, they are not exclusive) Netorare = ! (The MC doesn't care, he doesn't humiliate her or SPH, the MC doesn't lose his wife's love and respect...)
This isn't telling the story, it's just showing the player what to expect from each genre and its modifications.
People see fetishes differently due to this scope, leading to contradictions in fetishes. For me, harem and netorare fantasy are like that.
Harem = All the girls in a relationship with the MC are his and exclusive; there are no romantic or sexual relationships with other men. The women willingly accept that the MC has other women. It also includes the personality and appearance and the size of the MC's penis which will be more similar to the Taurus.
Netorare = This is the loss of the girlfriend (wife) to other men with elements of jealousy, humiliation, and SPH, with the transformation of love and affection into hatred and contempt. Here, too, the behavior is specific to the MC as an indecisive, hesitant, fearful cuckold, and the MC with a small dick who does not satisfy his wife sexually.
That's why these tags seem contradictory to me, as open is the opposite of closed, high is the opposite of low.
The MC is betrayed by his wife and separates, hence the Netorare tag. Then he starts a harem, or does he start with a harem and lose his girls? Or the traditional harem and netorare don't fit into your game and you can't find Tags that best define it (which I think are very bad F95, they could be more specific and with more variations).
You can use the gender space to give more details about the fetish beyond the common usage of listing present and future tags and what will not be in your game.
As you are the developer, you can better develop the details within the fetish, making your vision clear. I say this because a game can have a betrayal as a hook but not be the focus of the game and still receive the netorare Tag.
Just a suggestion
