Usually these kind of stories starts off with a FL wronged in the prior life and gets a 2nd chance. However in this story, The FL is trying to correct her wrongs.
There's a common theme referring to the scent (hence of scent of time)

The leads Zhou Ye & Wang Xing Yue is a good pairing visually.
Sets/production overall decent although inconsistent. Costume & accessories are beautiful especially for the FL. Then there are props that looks incredibly cheesy fake too.

What killed this drama little by little ...................
1. Poor choice of dubbed voice for the FL. Even when her facial expression is on par with the mood, the voice didn't follow. Actually it sounds like 2 different dubbed voices. One sounded older but either way, it was not good.
2. Mu Yao -- I was wondering how they picked someone who can't act AT ALL. Apparently she's some internet celebrity and end up getting this supporting role with enough lines that can kill a drama. So that happened.
3. OST overkill. It's a nice song but the ONLY song which they play bits of it 10x per episode x 30 episodes ....
4. Over smoothing of people's skin especially of Huan Rong Zhou. He has a wax figure face at times.

Potential not fully realized but not bad overall.
