Ken Takakura is Not a Mermaid by @grabdog
As long as no one knew, he could pretend that Ken Takakura, the human boy, still existed. But he knows, he’s always known, that who he was died that day almost ten years ago, when he’d been lost and shivering and had stepped into the pool of water in the sea cave in Scotland because it seemed so warm and he was so, so cold.
(extremely good characterisations in this one. they are beautiful disasters. also, the sequel fic has some of the best horror i've ever read, in any fandom)
