Mysterious.

I've been wondering: how do Korean Internet novels work, exactly? I was totally unfamiliar with this term until a few years ago, but then I started watching K-dramas, and they're all about the internet novels. The heroine of Full House wrote internet novels, and Wikipedia tells me that My Name is Kim Sam Soon and The 1st Shop of Coffee Prince (two of my favorites) were both based on internet novels. But what are they? Do people pay to read them by chapter? Can you buy print copies? Are any available in English?

My mind, it is inquiring. If you have any answers, please drop me a line.
