The line comes from Xenoblade Chronicles 2, the role-playing game released for Nintendo Switch in 2017, where long journeys, close companions and painful partings give short farewells a heavy emotional weight. As players clipped memorable dialogue and shared it beyond the game, this brief goodbye began circulating on its own in edits, tribute videos and memes. It has stayed useful because it needs no setup: even viewers who have never played the game instantly recognise a farewell, making it an easy shorthand for loss, nostalgia and characters who will not return.
