For those who can't get enough just by the audio of the song what are you waiting for, go and watch the mv because once you watch it heck even while watching it you will smile like a dork.
The mv(music video) which starts with a piano sound is enough to catch the viewers to stay watching till the end of the mv. Compare to their lucifer mv, hello is more cheerful with a lot of colors and smile in the video. Not forgetting their sleek dance move, they manage to charm all their fans once again.
I am sure Shawols(Shinee's fans name) would be happy with this mv.
