When the Sun Rises, I will...
Bilbo Baggins of Bag End was not a very respectable Hobbit. No respectable Hobbit had a sword and crossbow hanging in their home, nor did they have Dwarves as family. But Bilbo Baggins did, and all of Shire knew of his husband, blacksmith Thorin Oakenshield.
When Bilbo comes home to find his Husband earlier than expected, he learns of a quest to reclaim Erebor. It is a death mission. Bilbo knows that Dwarves are stubborn creatures, and none more than Thorin himself. But nobody said that Bilbo himself was any less stubborn.So he will follow his dearest husband across all of Middle Earth, through plains and mountains and forests, all while hiding the true nature of their relationship (Dwarven politics never helped anyone), brushing off some old wounds (and getting new ones) and finding out new things about the dwarf Bilbo calls husband (and his extended family).
Nobody ever said love was easy, after all.
