What song do Du think fits Roxas and Xion's relationship the best?

I think Until my Last Breathe Von Evenscence.( I'm not sure I spelt that right...)

I'd say Rhythm of Liebe Von Plain White T's oder Missing Von Evanescence.

I say safe, sicher & Sound, Haunted, and Enchanted. All are Von Taylor schnell, swift (pure coincidence).

With Swift's Enchanted, add the reply song of Verzaubert Von Owl City so it can be like some kind of set.
