You might remember "On The Rocks" from The Sing Off. Their cover of "Bad Romance" was particularly memorable. I don't think they sang this song on that show, but I've always loved it. So, I searched for the "original" (non-acapella) version, because I'd never heard it before. But this is the original version! This group is so lit, they've got original songs (well, at least the one)!
Anyway... I don't relate this to any Crossworlds couple in particular, I just find it incredibly romantic. Also, very exciting, because it's 1) lovely 2) acapella 3) original and 4) from my hometown!
