Why do you think that a particular kink needs to be equally applied to ALL and ANY characters? Clearly, some character types are "locked into" scenarios that only their path unlocks.
And that is exactly why I am advocating against the "cuck content" being added into Our Red String
AT THIS POINT!
If it had been advocated for sooner, say around the 3rd-4th update, I would have been fine with it. Especially when you consider that several characters had either not been introduced, or their general overall personality types hadn't been fully ironed out as much as they are now.
Back then, you had far more "wiggle room" in order to figure out which characters it would work for the best, as well as figure at least 2-3 different methods of obtaining that 'end-goal result' being spread out over another 2-3 updates. As well as having enough time to establish which characters such content will NOT be appropriate for, and establish those "block offs" over 2-3 updates.
So, going around the concept of 3rd update, with an additional 2-3 to iron out pathways, that would bring us up to 5-6 total versions where 'cuck content' pathways would have been clearly designated in some way. Personality matches with enough time to build relationships, options to establish the 'cucked male' and 'bull male', even possibility of "cuck-queen content' so that the entire concept is Lena's to explore and enjoy as well.
But that is all based on reaching version 6 at MOST! We are now ON version 8, about to see what version 9 brings us and the current level of advocating for 'cuck content' makes zero sense.
Not because the general concept of 'cuck content' could not, or would not, work as a concept in general. But because it is now basically impossible to properly apply now that we KNOW the general personality types, the relationship pathways AND the overall game design of playing 2 sides at once. It is simply NOT in the best interest of Our Red String as an overall project, to bring in this type of content AT THIS POINT IN TIME. It is like someone having a grilled cheese sandwich and someone suddenly demanding that you toss some tuna-salad between the slices of bread AS you are putting the sandwich itself together. It simply does not WORK as an idea at this point.
And I'm not against 'cuck content' when it is properly handled. It can be rather entertaining to play in the proper format. And for me, on a personal level, it is far more entertaining to play out when the MC is female-only. I don't like it when playing a Male-MC, but can at least be entertained by it with Female-MC formats.
However, be it a good or bad concept in general, still doesn't matter in this particular game format. By playing both sides, it opens up the undeniable issue of having to be 'content repetitive' if I have to play one side bringing up to the topic, then the other side considering it. Especially when I know that by doing so, I am willingly going to then cut off content from BOTH sides of the game down the road. It bogs down the creative process for Eva, and it diminishes the enjoyment as a player.
And again, not because 'cuck content' doesn't work as a game element, in and of itself. It is because there is a point in a game's progress where adding additional content DOES mean actually wasting time/effort on the creative side and player side.
A perfect example of this would be to attempt to make the older sister in Girl's Life as a main player option. It is far too late to do that for the MAIN game design. You can make it work AS A MOD, but even then is the project WORTH the time/effort to include it in a mod when it may only entail maybe a single game-year?
TLDR: There is a time and a place. And at this time, it is too late. And since it is too late, it really has no place to be considered worth pursuing as a "main addition".
