Lost ABO fic about inter-pack arranged mating between pack alpha Derek and BAMF Omega Stiles
This is a fic I read a long time ago on ao3. I remember that Derek was BH pack Alpha and he had to have an arranged mating for pack relations or because he needs a strong Omega to lead with him. I can't remember.
He mates with Omega stiles from another pack. I think Stiles' dad was the other pack's Alpha. The pack and Derek underetimate Stiles and act cold with him. Stiles is very independent and hides his full potentials but wants to help the pack.
I remember there was another Omega who wanted Derek and they insult Stiles and can't understand what is so special about him that Stiles' pack chose him for Derek.
There was also mystery unfolding and a danger on the way. It was a slow build so there was no romance between Stiles and Derek yet and they were just acting out their roles for the pack.
Even if you don't know this fic, I'd love reccommendations that are similar :) basically alpha Derek arranged mating with omega Stiles for the good of their packs
