Archive of Our Own has the deepest well for that pairing, hands down. The tagging system is precise enough that you can filter for 'Hajime Nagumo/Yue' and then add 'Romance' as an additional tag, and you'll get exactly what you're looking for. I've found over 400 works there where that relationship is the central focus, ranging from missing moments during their time in the abyss to modern AUs where they're college students.
Honestly, FanFiction.net is hit or miss. There are definitely fics there, but the search function is a nightmare. You have to wade through a lot of 'Hajime & Yue' gen fics or harem stories where their romance is just one thread among many. Some real classics are hosted there though, from before AO3 became the dominant platform.
A niche spot I sometimes check is Pixiv's novel section, but it's almost entirely in Japanese. The art is stunning, and sometimes there are short novelized pieces attached. It requires more hunting, but the vibe is different—often more atmospheric and less dialogue-driven, which can be a nice change of pace.
Wattpad's algorithm pushes the most popular tropes hard, so you'll find a lot of 'Bad Boy Hajime' or 'Vampire AU' stories there. The quality varies wildly, but it's good for a quick, tropey read when you're not in the mood for something dense.

There's an interesting split in how people handle them. A lot of fics put them through the wringer first—Yue pushes Hajime away because she's a royal and he's 'just' a commoner, that whole dynamic. They'll lean hard into the initial tension from the show. But then, the development often bypasses the slow political maneuvering you might expect and jumps to Yue secretly training Hajime or saving him when his own magic fails, which flips the power dynamic in a fun way.
What I see less of is fics that really sit with Yue's long lifespan and how that affects her. Some good ones have her wrestling with the ethics of getting attached to someone who'll be gone in a blink, while Hajime grapples with not being able to 'catch up' to her centuries of experience. That's where it gets compelling for me, more than just rehashing the classroom rivalry.

I keep seeing this question pop up in the community, and honestly, the most emotionally tense plots are the ones that mess with Hajime's established, overpowered reality. His whole thing is being an unstoppable force in a fantasy world, right? So the real tension comes from taking that away. A plot I saw that stuck with me put Yue in a situation where her bloodline powers were slowly killing her, something Hajime's artifacts can't fix. His frantic search for a cure, paired with Yue hiding her worsening condition to not 'burden' him, creates this heartbreaking push-and-pull. It's not about fighting monsters; it's about fighting fate itself, and his powerlessness makes him more human and desperate than the source material ever allows.
Another angle that works wonders is exploring the permanence of their bond outside the isekai context. I read a story where they were somehow separated, sent back to their original worlds—Hajime to modern Japan, Yue to her vampire kingdom centuries in the past. They can only communicate through a magical diary where their writing appears years apart. The slow-burn agony of knowing each other exists but being utterly out of reach, combined with the fear that the other might move on or die waiting, is a special kind of torture. It's less about immediate conflict and more about a deep, lingering sorrow that seeps into every chapter.

Honestly, a lot of writers seem to lean on the same handful of tropes for Hajime and Yue, and they can get pretty repetitive if you're not careful. The most obvious one is probably the immortality clash—she's an ancient vampire princess and he's this sort of functionally-immortal dungeon-diver with OP powers. That setup creates a weirdly reversed 'who outlives who' anxiety. It's not her worrying about him aging and dying; it's more like she's the one with centuries of trauma and he's the 'new' immortal trying to pull her into the present.
Another big one is the emotional restraint vs. possessive devotion dynamic. Yue's love is obsessive and all-consuming, which some fics play as a source of conflict when Hajime's pragmatic, mission-focused mindset brushes it aside. But I've seen more interesting takes where the conflict is internal for Hajime: how does someone so brutally practical handle being the absolute center of someone's universe like that? Does it scare him, or does he just accept it as another part of his chaotic life? Fics that skip past that introspection feel shallow.
There's also the 'harem tension' angle, which, ugh. I get it, it's canon-adjacent, but so many stories just use Yue's jealousy as cheap drama without exploring the actual negotiated polyamory the series hints at. I'm much more drawn to fics where the conflict stems from their differing moralities—his willingness to slaughter versus her more detached, ancient perspective on life and death.
