First KARA song that I heard was 'Break It', but for some reason it didn't really stick to me, so I didn't really bother to look into their profile (maybe because at that time I was sooo into SNSD...I still am btw...hehehe).
Then when they came back with Pretty Girl, I thought, its quite a good song, but it still didn't leave a big impression.
But when I saw their comeback stage for Honey, I was like . The song grabbed my attention and it was such a good and happy song. From there I pretty much googled everything about KARA and since then I have been a big fan of them.
