Very sweet
All of the settings in this are gorgeous, really wherever they filmed this is a fabulous place. My only complaint about them at all was that the flowers in gazebo scene block our view of his guitar playing (and of the guitar in general, which is a shame because it looks like a beautiful instrument). I really like the time progression idea of that setting though, and we do get a few good looks at the guitar as the MV rolls along.
Story-wise the MV is cute and heartbreakingly adorable in all the right ways. I love how they have her actually say the quotes in the song, that is a very cute technique and one surprisingly under utilized. All in all it's very cute. It's pretty uneventful, but it does well to expand upon the song's lyrics which are beautifully sweet and specific. Musically, it builds, it's got pretty good harmonies, the song's form is simple but the sections are well delineated; it's a very sweet song. I'm not a huge fan of it, but it's still a well made track. There's no real oomph behind it, no spark or sweeping rush to really get your heart pounding like the lyrics say the narrator's is . . . Still, good track, good release over all.
