If you are looking for a chinese historical drama that is about the love story between a quirky concubine and the Emperor, don't watch this: the summary is basically telling you what happens in the first two episodes, after that the story gets completely stuck.
The romance is NOT the focus of this drama: every episode is about a certain character and his certain problem and on how the heroines try to help with it. There is no real plot, or rather: the one that seemed like it was going to become a real plot abruptly ended in the middle of the series. After that, the relationship between Mengfei and the Emperor doesn't develop or change anymore, and it's not like the drama had really been about the romance before. Sometimes the Emperor doesn't even show up in the episode or only for a couple scenes.

I really liked the concept, so I sticked till the end hoping that thing would started to move at some point, but no, it didn't happen. I liked the characters of the concubines, especially Meng Fei, but I was so pissed at the summary that it completely ruined this drama to me.

Anyway, here is the real summary to this drama:
"Witness the life of four unconventional concubines and their friends in the inner palace, while they create problems and encounter problems, but always stick together and overcome the little nuisances of life. Meanwhile, one of them may have a couple of cute scenes with the Emperor."
