I don't mind removing the harem tag if it confuses people. I already put in the request.
The harem tag exits because some women in the game will only involve themselves with the player (No sharing).
There will never be the option of you losing your wife. She is written to be your loyal wife that is willing to do anything for you.
I use the netorare tag because there is no netorase tag.
Before continuing, I must say that I really like your game. It's wonderful that it breaks from the norm, straying outside the common culture found in over 90% of Netorare and Netorase games. I wouldn't classify it in any of those routes. For me, there's an open marriage route; both have two adventures. We already know Lucas likes to watch Lucia, so he'll develop a cuckold fetish too... There's also a shared route where the main focus is Lucia's extramarital adventures.
I wasn't criticizing you for using the tags, but rather trying to exemplify my point of view. Fetishes go far beyond the simplistic notion of the husband knowing or liking, especially if you look at it from a Japanese perspective; there's a culture and an expected behavior.
Aaron and Lucia are interracial, but Aaron isn't a BBC in his behavior, manner, and relationship with Lucas and Lucia. It's even strange and seems out of place, given how accustomed we are to BBC characters. And it's very good that it's that way.
