Man, I get this question a lot from fellow 'Harry Potter' fans! The short answer is no—Viktor Krum and Hermione don’t end up together in the books. Their relationship was more of a brief fling during the Triwizard Tournament in 'Goblet of Fire,' and while Krum was clearly into her, Hermione’s heart wasn’t fully in it. By the later books, especially 'Deathly Hallows,' she’s all about Ron, and their dynamic becomes one of the series’ core romances.
Krum does reappear in 'Deathly Hallows' as a guest at Bill and Fleur’s wedding, but there’s no hint of lingering feelings between him and Hermione. Honestly, I always liked Krm as a character—he was this brooding, talented Quidditch star who added a fun layer to the Yule Ball drama. But Hermione and Ron’s bickering-turned-love story just felt more natural in the long run.
