Step was my introduction to KARA. I happened to watch the video on YouTube when it came out and I absolutely loved the catchiness energy of the song, their coreography and how beautiful they were. But I have to confess that, not usually being a huge fan of idol pop groups, it didn't go beyond that.
Not much later, though, I accidentaly stumbled upon Honey and I was once and for all captivated. I mean, it's such a sweet and delightful song. Very poppy, yes, but in a good way, not in the stereotypical K-Pop bombastic/outrageous/attention-grabbing way.
So I went after the rest of their discography and was really impressed. Also, their personalities really charmed me. One thing that called my attention as well was the production and the instrumentals. So I researched and learned about Sweetunes as well. Now I'm a big fan of them both!
