AU where Asgard was never destroyed and Loki is finally able to be in a relationship with Fandral who lived. Hela and Thor are co-ruling Asgard after arguing over who was the rightful heir after their father's death. Thing is, despite Asgard flourishing and their people healing, En Dwi Gast hasn't let the idea of having Loki go, and invites himself over to try and take Loki for himself

+The Warriors Three and Sif are all alive
++Grandmaster/Loki is all extremely one-sided
+++When his arrival is announced, the Grandmaster doesn't even now or anything, the second he walks into the throne room he makes a beeline for Loki and kisses the living daylights out of him- Fandral then decks En Dwi Gast for daring to touch his prince when he's obviously uncomfortable and En Dwi Gast is an unwelcome presence
++++Grandmaster is jealous that Loki is with Fandral and will find ways to interrupt them on purpose he even bothers the Warriors Three and Sif about them to see if he can find any weakness in Fandral to convince Loki he's the better choice even though Loki and Fandral are happy with each other
