A random late-night search led me to this piece called 'Subsidence' on AO3. I wasn't expecting much, but the way it handled Atsushi's recovery from his time in the orphanage really stuck with me. It's not a huge plot-driven thing; it's mostly quiet moments where he learns that needing help isn't a failure. There's a scene where he tries to secretly clean the agency's bathroom at 3 AM because he feels he hasn't 'earned' his place, and Kunikida finds him. The writing didn't make it a big dramatic confrontation, just this tired, gentle conversation over spilled cleaning supplies. That felt more real to me than any epic battle.
Sometimes the smaller fics, the ones that just sit with a character's damaged psychology, get the growth right. He doesn't become magically confident. He just learns, slowly and painfully, that the world won't end if he accepts a cup of tea someone made for him. That progression felt earned, you know? I've reread it a few times when my own head gets loud.
