I’ve been diving deep into the Mikasa/Annie tag on AO3 lately, and the slow burn fics there are chef’s kiss. There’s this one called 'Frozen Flames' where they’re stuck in a cabin during a blizzard post-war, and the tension is so thick you could slice it with a blade. The author nails Mikasa’s guarded warmth and Annie’s reluctant vulnerability—every glance feels like a loaded gun.
Another gem is 'Thawing the Ice Queen,' which rewrites their cadet days with Annie actually trying to connect. The pacing is glacial (pun intended), but the payoff when Mikasa finally lets her walls down? Worth every paragraph. The fandom’s obsession with enemies-to-lovers really shines here, blending 'Attack on Titan’s' brutality with tender moments that feel earned, not rushed.
