This story is My Fair Lady meets Ancient China. I really enjoyed it. There were times when the story dragged a bit--my interest would be elsewhere at times or I just got bored--but I'm glad I pushed through. Yan Ling and Fei Long are great characters, Fei Long's characterization as a steely man of honor was very well done. Yan Ling was sweet, and her journey of self-improvement tugged at my heartstrings. Also, Li Bai Shen is amazing and deserves all the good things.
I loved, loved the ending. I live for HEAs. I had no idea how it was going to end (which made it really hard to enjoy that sex scene), but I'm glad it was solved that way. Everyone was happy and obtained their heart's desire.
