Almost each couple and everything I watch nowadays somehow reminds me of Damon and Elena.
But to name one I would also pick the Beauty and the Beast (although they are both really gorgeous and Damon isn't a real beast), but I watched the Disney movie lately and there were several things that reminded me of Delena.
1) Her being afraid of him at the start and losing that with time.
2) Them fighting with passion and fire while she is not afraid to stand up to him.
3) Him skrewing it up several times.
4) The love and affection between the two of them always being present somehow.
5) She bringing out the good in him and "saving" him with her love in the end.
... to name just a few.
