Ok, is my english this bad or is this twist bullshit?
MC was never a Human, he scammed many people and killed his Father, every Plan was only for his new Family.
and how is immortally this bad? MC was almost death without this dragon chick and why should he loss his humanity, this is a new World ...
I mean he could explore this World with his Harem, make his new Family a Part of the Harem (first Arcs implied they are more).
first his Aunt and the Sex with them was always a Bait, I believe his Father raping all three is more likely, than MC haven sex with them
