honestly, the fics that gut me the most aren't the ones that just retread canon tragedy. There's this one story called 'postage due' that lives rent-free in my head. It's an AU where Ash never went to New York, but they still find each other later through letters. The emotional depth comes from the quiet, aching loneliness of two people writing to a version of each other they've built in their heads, and the devastating beauty when they finally meet and have to reconcile the real person with the ghost they've been talking to. It's a slow, meticulous character study that builds its impact through small details—the texture of the paper Ash uses, the specific shade of ink Eiji favors, the spaces between the words.
What makes a fic emotionally deep for this pairing, for me, is when it understands that their tragedy wasn't just the violence, but the profound, wordless understanding they had that was constantly interrupted by the world. The best writers capture that silent language between them. Another author, 'canticle,' does this brilliantly in a series of missing moment fics that just explore them existing in the same room, the weight of all the unsaid things hanging in the air. It's less about big dramatic speeches and more about the pressure of a shoulder against another, or the way Ash would watch Eiji sleep, trying to memorize a peace he could never fully let himself have. That kind of writing requires a really delicate touch; it's easy to tip over into melodrama, but when it's done right, it leaves you feeling hollowed out in the best way.
