I'm not saying you should reveal the ending (that's if you already have it written and/or planned), The only thing we want to know is will there be a Harem, yes or no? (Because many of us find it difficult to choose just one of the LIs), That is why before trying to move forward with the game it is preferable to know in advance what is planned, this in general terms, The same thing happens with other fetishes, so as I mentioned it is good to know what awaits us and if there will be forced things/fetishes/labels and so on.
Well, I'm not really planning to make an harem content. For the avoidable content, I'm considering including a blackmail storyline, but it will be entirely avoidable or part of an alternative route. For less intense content, such as femdom, I wouldn't make it avoidable, though I might include a warning beforehand. As for another example, NTR would also be avoidable. That's all I can say since I don't have a finalized or exhaustive list of fetishes and labels for the game yet.
