I always get pulled into the tension more than anything else. Most fics I've seen focus on conflict or trauma bonding, turning their complex dynamic into something resembling a doomed romance from the get-go. They start as rivals or enemies, forced into closeness by external threats, which isn't friendship so much as intense, codependent partnership under pressure.
Honestly, a lot of writers seem to struggle with the transition from that rivalry to genuine platonic care. The 'friendship' often feels like a temporary ceasefire before they inevitably kiss. I crave more stories where the trust develops slowly, built over small, mundane moments after the dust settles, not just during dramatic life-or-death scenarios.
It's almost easier to write them as soulmates than as two deeply flawed guys who might actually learn to understand each other. I read one recently where they just... fixed up a house together, arguing over paint colors, and that quiet, bickering companionship hit harder than any epic betrayal arc.
