The story starts with an arranged marriage of our main leads Shen Du and Yan Xing. Shen du is the head of one of the department of justice I guess. Yan Xing is a scribe who wants to be a female official. Shen Du's father committed treason and his whole family was annihilated but he was pardoned by the empress dowager. However he wants to clear his father's name. So the couple solve different cases along their journey. This is the simple gist of the drama.

I rate this drama 7/10.
The plot was lacking soo manyyy thingss. The cases don't make complete sense. They tried to interconnect different cases but the execution was very bad. The female lead pretended to be smart but there her arguments were not that convincing. Too impulsive. Trying to solve everything herself without a care for others. I could not tell where the story was heading. 40 eps was a bit too long and draggy.
Undoubtedly, Shen Du was the best character here. I think this was Ding Yuxi's best performance yet. He lived upto his character's name. He was the only cautious person in the show. Planned everything ahead. The female lead's acting was also really good. I was most impressed by the acting of Lai Longzhi.
The characters dynamics was really weird. Nothing was clearly stated. The sudden tribe and their arc was so abrupt. What was the deal with Chen Huoe. The girl who was always with empress dowager. What was even her purpose? Everything seemed too messy with no proper explanation to viewers.

If you are looking for a cute drama with some bits of mystery then go for it. But do not expect to find logic here.
