I only have 2 friends who are k-poppers, both like KARA and the other likes Nicole very much and other one likes Seungyeon, but they don't call themselves Kamilia.
One of my friends who knows k-pop but doesn't listen to it also knows KARA, she bought their Best Clips DVD for me, how sweet of her! ^^
Oh and I have also one friend who listens to all kinds of music, also some k-pop and she really liked KARAs STEP when I showed it to her, she said she listened to it like 20 times in a row haha
