Make sure to watch the whole thing, the end really gets me...
I think it would've been a great vega(n) video if it wasn't for them using some actual fish in it too (if it's real fish, looks like it)
Ironically, the song itself has nothing to do with is so you can ignore it if you don't like it (it's about them falling for a girl, which is not so accepted yet in Asia so another reason I love this song)
