Strangers, an iceburns oneshot

[Frozen; Hans x Elsa; 10 years post-film; oneshot.] She's not sure if she's really seeing him, or if it's just another phantom conjured by her memories, passing her by along the busy street. But she keeps coming back to him every night, to learn about his past, his present, and how things might have turned out if they were just two, ordinary people—just two strangers.
