I think so cause... That's his bio uncle (didn't finish to the end but I think the mom and ML are bio siblings)
Sorry, they're step siblings.
He isnt the Bio Uncle, the omegas mom was The Alphas Step Brother

they're not.
Dad married older sister's mom she was already pregnant then the mom dies, dad married younger brother's mom.
They're not siblings by blood.
The older sis' mom married the dad because of money.
is this incest
