I really don't know if I am on the correct point to add my wish to read something like an Alpha-Beta-Omega QAF.

Here goes my suggestion: 

Brian is of course an Alpha. Justin is an Omega - a rare, seldom kind, and male Omegas can give birth. 

Maybe in this story Brian refuses to confess he is in love with Justin, not  knowing or ignoring the consequences for  Omegas, who can only bound once to their true Alpha ... or get  hurt, maybe even die.

Justin is too proud to play the little Omega in Distress card ... 

I wouldn't mind some Anti-Michael. 

But ... only Happy ending, please, meaning at the end Brian & Justin together and in love, I can't read anything else. 

Why I don't write that story by myself? Unfortunately my English is too bad. 

Maybe someone can take this, I would be very very happy. Thanks.
