After a brutal storm leaves Katsuki Bakugou stranded and nearly dead, he washes up on a hidden fairy deck where Y/N—an otherworldly being made of stardust—takes him in and nurses him back to health. As he recovers, the rest of the fairies swarm him in chaotic fascination, but Y/N is the only one who treats him like a person, grounding him in a world that isn’t his. She falls first in quiet, unspoken ways, while he resists until the thought of leaving her behind hits harder than anything the sea ever could. When he finally asks her to come with him, it isn’t to claim her—it’s because, for once, Katsuki chooses something that chose him first.
