Looking through Archive of Our Own last week, I stumbled across this absolute monster of a fic called 'Nightingales'. It's an AU where Shisui never dies, and he and Itachi defect together before the massacre, becoming these sort of shadowy, nomadic figures. The prose is dense, almost literary in places, which might not be for everyone, but the author nails the unspoken intensity between them.
It’ channeled that quiet, weary loyalty they have in canon into something heartbreakingly domestic. There’s a scene where Shisui is meticulously grinding tea while Itachi just watches from the doorway, and not a single line of dialogue passes between them for pages. You just feel the history. I will warn you it’s a slow burn in the truest sense—we’re talking 200k words before anything explicit, and it meanders into world-building about minor clan politics, which I actually loved. The downside is the comment section is full of people begging for faster updates.
I burned through it in two days, and it left me weirdly melancholic for a week. Hits different when the author clearly isn't just ticking romance tropes but actually understands the weight of their shared trauma.
