I just watched the PV's and I love them!
Inside is my favorite, but they are both great. The concepts fit too. She mentioned Inside is from the pov of a girl who's happy with her surrounding and its PV is really happy. And Outside is about a girl who wants to escape so that fits too ^-^
I'm probably stating the obvious
Her 'ah-my-gawd-a-monster-is-chasing-me ;_;' acting skills were fail though XD
