I love this doujin so much!It not only describes the sex moment,but also many thing about their love and their inside.I think it should be seen by Hiromu Arakawa herself!
I like how this pretty much manages to make a hentai involving them and staying in character. Especially with Ling's desire for power and Lan Fan's sense of duty while also managing to give them a rather 'happy' (as in good ending without leaving too much unexplained) making this a rare hentai doujin with an actual plot. Above it all I also loves the art, I actually think the use of watercolor brush strokes rather than a pen help give this a sort of ambiance that it really amazing. 10/10.
