Well, i don't know how this work so it may be a little crazy for me if someone answers this. 

I want to write an omegaverse story but one of the main characters as a delta and there's not much information about it. Of course is going to have an angst plot because of his delta status but, how can a delta have a happy ending with an alfa after being born as an alfa and letting one dominate him in the name of love? If you can help me, then i'll be really happy.
