Has this ever been done on a large scale? I know spacer did something like this with the MC's aunt basically forming the harem around her nephew but i don't recall ever reading a harem novel were all the girls/women agreed that they wanted to specifically try to reel in a certain family member to base their harem around and the seduction process in doing that.
Note, im not looking for a novel we're all the girls agree to share the mc after he starts dating them, i'm looking for a novel that starts off with all the girls making a deal to go after the mc, making him see them as valid love interest, past the incest, past the age, also accepting a harem in modern day times.
Let's be honest if 4-5 women walked up to you in 2021, asked if you would like a harem and then if those same 4-5 women we're family members it would be unbelieveable (they would literally have to crazy right?) which is why i thought of this story idea.
TLDR: How to make an unbelieveable harem story about family females going after a guy believable.
Hope that made sense lol.
