Continuation of this post of the Cinderella AU where Bilbo is turned into a dwarf by Gandalf, his fairy godmother, to attend an exclusive party.
Later, when Thorin realizes Bilbo can’t understand Khuzdul he believes that Bilbo has grown up under an abusive family (no) and has been wrongly depraved all his life of Mahal’s precious language (also wrong). He later takes upon himself to teach Bilbo Khuzdul. Bilbo always leaves before midnight and Thorin thinks he’s under a curfew from his abusive family (wrong too) and follows him home.
