Illegitimate son of the dad. The dad brought him to their household back when the mom was still alive. And when the mom's condition got worse, I think it was when the eldest brother took the youngest with him and left middle son with the mom (he wanted to stay anyway).
Wait I thought they weren’t actually related? Cuz they sleep w each other
The youngest son isn't actually related to them in any way. His bio parents died in an accident and because his mother was the first love of the father he took him in.
Oh okay I just found out there was a spin off of them! Sorry sorry
so wait yall is the youngest brother the illegitimate child or the father love child with another man?
