It's fine if there is optional lesbian content like a toggle off not like if MC doesn't choose to go along with the ladies they are engaged in the background , it must stay if there is a choice like a no there shouldn't be any with or without him.
I don't mean to engage in every single lesbian discussion because it might give the impression that I'm against this type of content which is absolutely not the case. I won't bring up other games because it isn't relevant to this game, but there are those with lesbian relationships/situationships or even lesbian-centered that I adore and love. Most of those though, are usually from a female protagonist perspective, which surprinsingly (or not) treats this theme which much more respect and care.
However, the inclusion of lesbian content in harem games is starting to get disproportionate. I mean, I've played/tried what, 30 harem games? And maybe two/three of them don't have (at least so far) lesbian content included/planned. That's a ridiculous balance. Sure, yeah, in some of these games you have a toggle to disable it or not, or you have a single choice in-game to decide whether to have that type of content or not. However, many of these games, especially in their final stretch, start to include a bunch of said content which, if you decide to avoid, you'll of course miss, so you'll have a half-baked resolution to your harem, because the intended way seems to always revolve around having your LIs fooling around in the end, as if it's always an inevitability.
The issue with most lesbian stuff in harem games is that it's usually treated as a pure fetish, on the assumption that every single guy in existence will always find it hot. And yes, many might, but context matters a lot. You might enjoy lesbian scenes purely on a porn aesthetic, but in AVNs, no matter how much people claim that these are just "pixels" or porn games, you get attached to the characters, so watching them doing stuff, especially without you, might sometimes be uncomfortable for the player.
Again, yes, it's cool if said content is optional/avoidable (not skippable), that should be almost always the way to go, without forcing you to go through content you might not enjoy and of course not forcing you to engage in it to get involved with certain LIs. That's also a common practice, some devs tell you that it's optional, but if you don't partake in lesbian content, you'll miss LIs, so in the end you won't get a full harem, which is basically what most harem players want.
The main issue in this game relies on the fact that it was stated and specified many times that said content wouldn't even be a part of it, so why bring it up again after years of development? Was it a false promise? Was it an attempt of trying to appeal to a certain crowd only to lie to them in the end? Because I prefer devs to be upfront about their content, even if it's not my cup of tea. You then might decide if you want to try their game or not, but at least they're fully honest, and that's always a plus.
