and yet, the story isn't really gone, is it?
it's still there, everything is always there. even when the plot comes to an end, the story and the world and the characters all continue existing
not in any "real" ongoing sense, of course, but more in the way that they continue influencing you and keep being a part of you. the stories and the characters all carry on in your memories
it's more obvious if you're into fanfics, but they never really stop being there just because you reached the end
