The source material came from the the second book which is called the Pillow Book. For those who are disappointed with this not being a continuation of DongFeng's story on TOMPB, please give this drama another look by watching episode 24 onwards. The story gets better from there. In terms of story, the Pillow Book is way better than TOMPB.

So far, the leads have improved their acting from their previous drama. With their acting and story writing, they've done the book justice so far, especially with episode 30. I love how the setting is pleasing to the eyes too.
