You are my savior

Thorin, son of Thrain, is a Dwarven prince in the kingdom of Erebor. He lives in the Lonely Mountain with his siblings Frerin and Dis, his father Thrain and his grandfather, Thror. Thorin's life feels empty, he doesn't have luck with women and forging is the only thing to get him away from his dark thoughts.
Until one day, a hobbit appears. He seems like he has been wandering alone in the wild for a long time. He doesn't tell much about himself or his past. His past seem to haunt him. Still, Thorin deems the hobbit trustworthdy and decides to give him shelter. The company of this dwarf makes the hobbit, Bilbo, feel safe and at ease. Bilbo, for his part, makes Thorin feel loved and happier than ever. They realize that they have feelings for each other.
But what happens when Thorin's family finds out about the affair? And what about Bilbo's dark past...?
