I like the flow and concept of the story. The setting and all really fits it's parts.
All the characters shows important role.
The loyalty of the personal servant of all the characters is promising that they are willing to risk their lives for their madam/master and I commend the supporting role of aunt Jia here.

Everything was perfect and there's an unexpected twist, very unpredictable.

Though the story doesn't focus on the main couple but they stay in the subject which is the secret of Tian for being a homosexual.
It also shows how hard it is to be a homosexual in the past because everyone will judge you, no matter how good you are if you are homosexual you are being degraded.

The series is full of message, the love for mother and child, brotherhood, loyalty, it also shows how they protect their image, greed for power, and many more.

This is one of the series that I wish doesn't end.
One of the best BL series I have watched.
