This song I first listened to was doing warm up exercises during dance lesson 2 years ago and because of the brainwashed melody, I started to search for the song. But since I don't know any Korean pop song at that time, I had given up in searching.
Time flies and I can still keep hearing the introduction of the song in some incidence. Finally I knew the song by watching the K-POP commercial on Jade 2. Then I found all the video related to it. I was amazed when I saw B1A4 practicing the dance.... AHHH, it was so cool. And I love the dance so much.. （*´▽｀*）
