the story took place after the Tang Dynasty was being ruled by the female Emperor Wu. Mengfan and Mengfu were two sisters that were forced to work in the palace after their father was killed. they started from the bottom and each with their own ways, strove for a position higher up in their rank. Mengfan disliked the life in palace and was determined to remain uninfluenced by the negativity of the palace. Mengfu on the other hand, didn't mind the influences as long as it brought her a step closer to her dream.
with a distinct role between Mengfan and Mengfu, it was obvious who the Good or Bad sister were. it made their outcome obvious since karma was involved. however, the differences didn't help make these characters lovable. while Mengfan was determined to remain "good", she was quite an annoying character to look at as she separate everything clearly into black and white, and wouldn't take no for an answer. Mengfu was like a wild child, her character often seemed heartless but was highly relatable if compared to Mengfan. in overall, the series was enjoyable and fast paced. but most of the time, the clarity that the series tried so hard to portray just to separate the good from the bad was what ruined the series.
