Am not a fan of Dilraba and often avoid her dramas and I have never seen any dramas of Ren Jialun before this. But there is this one scene that took my interest and got me watch this drama (The scene where Yunhe had to bathe Changyi)

Story: The story is not perfect.. there are too many boring scenes that I actually skipped. I Even skipped the first episode because I do not know what that purpose is. However the two leads were so adorable so I mainly watched their scenes - I kept rewatching their scenes again and again.
I read the novel after finishing the drama and I really wish they kept some parts of the novel.
I wish they didn't change the reunion from the novel - Their reunion in the novel was so beautiful unlike in the drama where Changyi was acting as if nothing ever changed (Hey, I am sorry forgive me please stay) there was no show of remorse or regret that Changyi in the novel had, there was no character development which Changyi had early on (when he decided to destory Yun He's body in order to save the north)

The novel showed us the love Changyi has and the trauma that Yunhe's betrayal has given him. In the drama it just made Changyi look so narrow minded.

No amount of crying and cheesy sad lines from the ML and FL - made me sad. Unlike in the novel where I really cried a bucket.

They added so many extra parts - so unnecessary.
I hate that they made Lu Haoqing the second ML - forever longing for Yunhe.

Casting: The casts did great job, especially the two leads - if they casted someone else as Changyi and Yunhe I doubt I will be able to finish this series.
The chemistry at the start of the series was good. You can see that they do get along. The friendship between Changyi and Yunhe.
However in the later part of the drama, it almost made me wonder if the two leads had some issues with each other or the shooting because they suddenly felt so distant, even the ML look so tired and no longer trying to show any acting that he actuality showed in the first half of the series.
FL was steadfast, he acting isn't topnotch but it's passable.

I think I must praise the director but had to say I'm disappointed with the writers.

Anyway BW is not perfect drama. It is a drama that made me skip a lot of parts and just go straight to the MC scenes. It's a drama that will not work if not for the two leads. Since I was able to rewatch those scenes for countless of times. I will give it an 8
