Apocalyptic, end of the world love?

This is a pretty straight forward request, I’ve been SO hooked on Die With a Smile and If the World Was Ending lately they’re basically the only songs on repeat at the moment. I’m so intrigued by the idea of, “the world is coming to an end but all I want to do is be with you and watch it happen” but have no idea how to even begin looking for books with this premise.

Any and all suggestions are greatly appreciated! And it doesn’t have to be a romantic love either, I’d love any form of love that shines through in the dark days. Thanks!
