Matthew and Mary- Young and Beautiful 

SPOILER ALERT In honor of my literal FAVORITE t.v. show and its series finale, I give you Matthew and Mary from Downton Abbey. Watching this show and this couple is a roller coaster of emotion. And it maybe that I'm having a thing with Lana Del Ray, but I think her song "Young and Beautiful" goes beautifully with their story, becasue they never got to get old with each other. Their story was tragic and abruptly ended and this song is everything that their lives together should have been.
Disclaimer: I credit this wonderful, amazing show to Julianne Fellows and everyone else in the making of Downton Abbey. And this song is by the great Lana Del Ray.
