The core tension is always the clash between their ideologies, right? Mirko's relentless, upfront combat style versus Hawks' deceptive, behind-the-scenes strategizing. It's the embodiment of 'might makes right' against 'the ends justify the means.' Most fics I've read build on that professional rivalry, having them butt heads during missions or in meetings, which naturally spirals into something more personal. The conflict gets really interesting when Hawks' double-agent work for the Hero Public Safety Commission comes into play, because Mirko would absolutely despise the lying and manipulation, even if it's for a 'greater good.' She values raw honesty in a fight, something Hawks can't afford to give. A lot of writers use that to create a really charged, slow-burn enemies-to-lovers arc where the real struggle is about trust.
Honestly, I think some authors lean too heavily on that framework without exploring the quieter conflicts. Like, what about the strain of Hawks constantly having to hold back, to not fully unleash, around someone as explosively powerful as Mirko? There's a potential conflict in physical restraint versus the desire to connect that doesn't get enough play.
