When I'm hunting for kiribaku fics, a surprising first kiss scenario turns up all the time: they're in a training accident, covered in dirt and bruises, adrenaline still buzzing, and Bakugou just... snaps. It's never gentle. It's a sudden, teeth-clashing mess born from frustration and that weird rivalry-fueled tension they've always had. Authors love using the high-stakes environment of UA to force the moment, like a villain attack leaving them both shaken and grabbing for each other. Makes sense, given their whole dynamic is built on physicality and explosive reactions. It's a shortcut to bypassing all the emotional talk neither of them would ever initiate.
I've also noticed a ton of fics rely on the 'Five Times They Almost Kissed + One Time They Did' structure. It's practically a genre staple. You get all the classic near-misses: Bakugou yelling and getting way too close to Kirishima's face, a shared blanket during a movie night, that one time Kirishima almost gets hit and Bakugou yanks him back... It builds the anticipation so readers can savor the payoff. Sometimes it feels repetitive, but when it's done well, focusing on Kirishima's quiet yearning versus Bakugou's loud denial, it really nails the slow-burn angst everyone secretly loves for this ship.
Then there's the aftermath trope, which is honestly my favorite part. Bakugou always acts like it was a mistake or a weakness, storming off and calling Kirishima an idiot, while Kirishima just stands there grinning like an absolute fool, all 'Ha! I knew you felt it too, man!' The kiss itself is often just the catalyst for the real story—how they navigate actually being together when their entire friendship was built on not acknowledging any of this. I keep reading because I want to see Bakugou's gruff, begrudging care, and Kirishima's unshakable loyalty shifting into something softer.
