Here are ILY:1 with illang (Firework), a summer song from last year that does actually include fireworks in the MV, albeit computer generated.
A section of the MV is set in Van Gogh's "Bedroom in Arles" . Unfortunately, the visual possibilities are not explored further. Some cute interaction with animals and the girls look pretty.
I suppose one could describe the song as tropical christian horse girl, which appeals to me, but which I also understand is not everyone's cup of tea.
