If I could rate this higher, I would. This is the most gripping webcomic I've read in a while. It's so good that the drama interests me more than the romance.
You might think it has a typical plot to begin with - female lead gets unfairly banished from the house by her own family and must walk the path of revenge - but the plot gets far more intricate. I couldn't stop consuming chapters.
Highly recommended.
