Fics like even if it takes all night (or a hundred years)

Lumine wants to save this world, in her own twisted way. Aether? He’d burn it down without a care. --- Aether's journey around Teyvat has come to an end, and he's tired. He's tired of being everyone's errand boy, of solving every problem the world presents him with without ever receiving anything in return. When he finally meets his sister again, he takes her hand.
