Well, we, monogamous crowd are usually quite, at least we are not that loud as harem-lovers, until it's too late.
So, Devs, sometimes get it in a way that their whole audience wants harem, which is absolutely not true, not even close.
And yeah, there are only few Devs here who said right from the start - this is MY fucking story and I will tell it in MY way, and they actually do stick to it.
But also it's just that not everybody is capable to bear with backlash and harassment, that's the problem unfortunately.
