I heard them from a JROCK group named SCANDAL during an interview they asked them what is their favorite karaoke song, Haruna Ono answered "Kara's Mister". I got curious and watched their MV and the rest is history.
Ignore them, they can hate all they want. They are filling their lives with hatred, *tsk tsk* poor them Let's just enjoy Kara's music and support them.
I tried dancing their Mister song. When I saw the MV I said "Too easy" but when I tried dancing it, it was difficult. I saw some tutorials and at last I learned the butt dance.
I thought Nicole Jung was the leader when I saw the Mister MV. That was also the first time I saw Kara, I heard about them but I don't know their faces.
