Yes, I watch it. I remember there was a thread on it awhile ago but it turn out to be "Incest is disgusting debate" thread.
As liberal as I am towards anime, this one had me at the borderline. There were parts that gave me a gut wrenching feeling. Setting the incest aside, it is a good romance story diving into a taboo topic that society nowadays despise of. This makes their relationship more interesting to watch it develop.
I would recommend this if you don't mind the incest part.
