Ah, I've read this before! (I think. In any case, I'm quite familiar with Shinjo Mayu.)
It's one of Mayu-tan's series that has more dark themes, I suppose. Like rape. Mayu-tan pretty much writes soft-core pronz for females. The nickname "Queen of Smut" has been pretty often, and I won't disagree. I think she looks too cute to write this kinda stuff. Anywho...
Her stories aren't really enough for me to QQ, but it's enough to keep me reading, and her drawing style is pretty nice to look at. Better than most mainstream, I daresay. This is one of her better ones, story-wise. It might just be because of my I ❤ HONG KONG mind, but it's interesting.
