Three short lines carry the whole story of a relationship, or at least something that mattered to the speaker. The poem never says who "we" are, and that gap lets us fill it in: lovers, friends, family, anyone whose bond has come apart.
The key move is how the word "nothing" shifts. The title promises it, and the second line delivers it: the two people "ended with nothing," no closure, no explanation, nothing left to hold. Yet the last line turns against that emptiness. "But remember everything" suggests that memory stays full even when the connection itself is gone. The speaker seems to be the one who remembers, and that is both a comfort and a burden.
The mood is quiet, bare, and a little bitter. There's no anger or dramatic grief, just a flat, tired honesty. The short lines feel like someone who has said all they can bear to say, and the lingering ache sits in what is left unsaid.
