It's definitely mentioned that Ahjo is the child of the alpha dad and a "mistress." However, it's only mentioned briefly and vaguely, so we don't actually know if the dad cheated or if it was planned or what truly happened. The most popular assumption is that the alpha dad cheated, but it hasn't been proven nor denied.

Did it ever get mentioned in the story that the alpha father cheated? Cus what if he is their son and he just hates him cus ahju looks like him and not like other kids who looks like the omega dad?
This is too confusing.And they are all shit. I knew feom the start they were gonna just use the mc.
