What Emotional Dynamics Define Bottom Kaeya Fanfiction Plots?

Any trope where Kaeya gets thoroughly emotionally dismantled works for me. He's a liar and a shield; putting him in a position where vulnerability isn't an option but an inevitable consequence makes for great drama. I've seen 'Hanahaki' done with him choking on crystalflies or wine-stained petals, and the idea of a love so physically consuming it betrays all his secrets is perfect. 'There Was Only One Bed' forces that proximity he'd normally deflect with a joke, but exhaustion or injury strips the performance away. Really, any trope that corners him into sincerity, where the mask has to fall not because he chooses to drop it, but because it's ripped off. Also, hurt/comfort where the 'hurt' is largely psychological. Having another character—Albedo, Diluc, even a Traveler—piece together his fragmented self through quiet, persistent care fits a bottom dynamic. It's less about physical dominance and more about someone patiently unraveling his defenses until he has no choice but to be seen. The power isn't in forcing him down, but in being the one person he can't successfully lie to anymore. That slow, reluctant surrender of control is the core of it for his character, I think.

I see a lot of writers get caught up on making bottom Kaeya's internal struggle all about the conflict with Diluc, which feels like low-hanging fruit. There's a more interesting tension, I think, in the way his performative flirtatiousness clashes with genuine vulnerability. He uses charm as a shield, so when that facade is stripped away in an intimate moment, the emotional whiplash is intense. It's not just about being physically dominated; it's about the terror of being truly seen when all your survival instincts are built around misdirection. Sometimes the best fics explore the guilt he might feel over 'using' a partner for comfort or distraction, seeing it as another layer of his manipulations, even if the other person is willing. That self-loathing angle gets under my skin in a good way. The conflict isn't always with the other character—it's often him fighting his own reflexes, trying to let go of control when his whole life has depended on maintaining it. I read one where he kept making snarky comments even in the middle of things because he couldn't shut the persona off, and the other character had to patiently wait him out until he finally cracked. That felt painfully real.

Kaeya's whole deal is being the guy who knows all the secrets but hides his own. Putting him in a bottom role in fics plays directly into that vulnerability he's always guarding. Authors get to pry that armor off, but they have to earn it first. The best stories use it as a payoff, not a starting point. You see a lot of 'comphet' or duty-bound Kaeya paired with someone like Diluc, where the dynamic hinges on Kaeya finally letting someone see the parts of himself he considers weak or unworthy. It's less about physical positions and more about emotional exposure. That moment where the carefully constructed flirtation drops and he's just... uncertain. That's the good stuff. It also lets writers explore his canon backstory—the spy, the inheritor of a doomed legacy—through a lens of trust and surrender. Who does this man, trained to deceive, allow to hold him when he's not performing? It creates a specific kind of romantic tension that's really unique to his character.

Alright, let's talk about bottom Kaeya because wow, does the fandom have a type. A huge chunk of it revolves around Diluc/Kaeya, obviously. It's the classic angsty, childhood-friends-to-enemies-to-lovers drama, and Kaeya being on the bottom fits that dynamic of vulnerability and submission that the tension demands. Writers love exploring his guilt, the way he wears his secrets like armor, and then having Diluc be the one to break through it—physically and emotionally. It's all about that cathartic hurt/comfort, the ‘I hate you but I still care’ trope played out in every possible AU from canon-divergence to modern coffee shop settings. Beyond the ever-present Kaeluc, there's a surprising amount of Kaeya/Albedo. The cold, analytical Albedo with the emotionally complex Kaeya creates this fascinating power dynamic where Kaeya’s usual flirtatious control gets dissected and reversed. It's less about raw angst and more about psychological unraveling, which is a fun shift. I've also seen a decent amount of him with Zhongli or even Childe, where the theme leans into Kaeya being outmatched by an ancient power or chaotic force, playing up his cunning against sheer, overwhelming strength.

The whole 'platforms for specific positions' question always makes me laugh a little. Like, are we searching by tag or by some secret handshake? Most people hunt on AO3, obviously. That's the main battlefield for 'bottom Kaeya' or any other ship dynamic you can dream up. The filtering system is unmatched; you just pop 'bottom Kaeya (Genshin Impact)' into the relationship tags, sort by kudos or date, and you're swimming in content. Some of the Zhongli/Kaeya stuff there is particularly good, all that ancient dragon/calculating knight power play. Though I've seen a fair bit on Tumblr and Twitter too, but it's way more fragmented. You find a thread, someone links a Google Doc, it's a whole scavenger hunt. Wattpad's got some, but the tagging is so chaotic it feels like digging through a bin without gloves. For pure volume and ease of use, AO3 wins every time. I just re-read a modern AU there last night that nailed his performative vulnerability perfectly.

Alright, so bottom Kaeya fic? That's a surprisingly specific niche even within Genshin Impact circles. Most of the dedicated stuff I've stumbled across is on AO3, hands down. The tagging system over there lets you drill right down to 'Kaeya (Genshin Impact)/Bottom Kaeya' and then sort by kudos or bookmarks. You'll find a ton of KaeLuc (Diluc x Kaeya), obviously, but also some really creative rare pairs and character studies that use the dynamic to explore his canon vulnerability under all that performative charm. The main trick is filtering out the huge volume of general Kaeya works. I usually exclude 'Top Kaeya' tags right off the bat. Some authors are amazing at weaving the power dynamics into the story so it feels organic—less about the tag and more about his characterization. Tumblr used to have more snippet-style posts, but it's harder to search now. Twitter/X is mostly art and vibes, not long-form stories. Honestly, if you're deep enough into a fandom to be hunting for a specific trope for a specific character, AO3 is basically home.

It's wild how a single headcanon can reframe an entire character, isn't it? With Kaeya specifically, him being the 'bottom' in a pairing, especially with someone like Diluc, flips the power dynamic we see in-game on its head. Kaeya's always portrayed as the charming, in-control manipulator, the chess master. But writing him as a bottom often explores the vulnerability beneath that. It's about him letting that guard down, the calculated flirtation becoming genuine need. The romantic tension doesn't vanish; it transforms. It's less about who's chasing whom and more about the push-pull of trust versus control. He might still initiate the verbal sparring, but the physical or emotional surrender holds all the charge. That shift makes the eventual catharsis hit harder, I think. When a character built on secrets finally allows himself to be truly seen and accepted in a more submissive role, the emotional payoff for the reader is immense. It's not a reduction of his character; it's an amplification of a hidden facet. The tension becomes about whether he'll allow himself this softness, and if his partner can handle the weight of it. It turns the typical 'enemies to lovers' trope into something more psychologically intimate. I've seen it done really poorly, where it just makes him seem weak or out-of-character. But when it's done well, it highlights his complexity. He's still cunning, still sharp, but he's choosing where to lay down his weapons.

Honestly I kinda bounce off most of them because they tend to default to a really simplistic 'sun vs moon' thing. It's all about Kaeya's deception and Dain's truth, the charming liar versus the cursed purist. I think that misses the richer soil. I'm way more interested in the idea of two people who've both constructed identities around colossal, world-shaping secrets, but one chose infiltration and the other chose exile. The dynamic isn't just opposition; it's a mirror held up at a weird angle. I read this one fic where Kaeya figured out Dainsleif's connection to the Traveler's sibling not through heroics, but through recognizing the bureaucratic evasion patterns in his stories—the same kind he uses to deflect about Khaenri'ah. That felt real. Their conversations should feel like two spies from rival agencies meeting in a neutral city, every pleasantry a probe. The tragedy isn't that they're enemies; it's that they're probably the only two people alive who could truly get it, and they can't afford to.

Kaeya's betrayal arc in 'Genshin Impact' is a goldmine for fanfiction writers because it layers emotional complexity with just enough ambiguity to fuel endless reinterpretations. The canon paints his past as a spy for Khaenri'ah against Mondstadt, yet his bond with Diluc—once brothers, now estranged—adds a visceral personal stakes. Fanfics often amplify this by exploring the unsaid: the lingering guilt Kaeya carries, or Diluc's torn between betrayal and their shared history. Some stories dive into Kaeya's self-sabotage, using alcohol or reckless missions as metaphors for his guilt, while others fixate on Diluc's cold exterior hiding grief. The best angsty reconciliations avoid easy fixes. Instead, they build tension through small moments—a shared memory of grapevines at Dawn Winery, or Kaeya bleeding out in the rain while Diluc hesitates to heal him. Physical touch (or lack of it) becomes a language; a gloved hand withdrawn too quickly speaks louder than monologues. What fascinates me is how writers weaponize Mondstadt’s themes of freedom versus duty. Kaeya’s loyalty conflict mirrors the city’s ideological clashes, making his redemption feel earned when he chooses Mondstadt—or Diluc—for real. Some fics even parallel his arc with Venti’s hidden burdens, framing both as liars who protect through deception. The angst often peaks when Kaeya’s mask slips: maybe he screams at Diluc during a storm, or collapses drunk in Angel’s Share, begging for forgiveness Diluc won’t give. The reconciliation’s timing matters too. Rushed makeups feel cheap, but drawn-out mutual pining where they orbit each other for years? That’s the good stuff. Bonus points if Jean or Adelinde meddles to force them into a room together.

It's this push-pull between vulnerability and protector energy that gets me every time. Felix as this endlessly kind but sometimes fragile force, Chan as this leader-type who feels the weight of the world but would never show it. The tension comes from the fact they're both pillars for each other. I've seen a lot of fics where Felix will have a nightmare or a panic attack, and Chan just knows without being told—the whole ‘silent understanding’ thing. But then there’s a twist I really appreciate when writers remember that Chan's not a robot; he has his own breaking points, and sometimes it’s Felix who has to be the grounding one. That balance feels true to what we see on screen. It’ certain amounts of physical affection in their canon interactions, and fics often amplify that into a whole language of touch as reassurance. It's less about grand romantic gestures and more about the quiet moments backstage, in the dorms, or on a late-night drive where the guard finally drops. A dynamic I find tricky to get right is the power imbalance inherent in the leader/member setup. Good fics don't ignore it; they navigate it. There's an inherent responsibility Chan has that makes any romantic or deeply intimate connection fraught with potential guilt or fear of favoritism. The best stories I've read make that part of the conflict—Chan wrestling with whether it's okay to want this, Felix worrying he's a burden or a distraction. When it's resolved through communication and mutual support, it's incredibly satisfying. I'm less fond of fics that turn Felix into a complete damsel or Chan into an infallible saint. The real draw is two people who are already strong individually finding a different kind of strength together, which is, honestly, the backbone of most ChanLix stories I bookmark.
