This show was really enjoyable for me as I've never seen an historical drama this good with crime investigation. I liked the clumsy duo of Su Jiu Er and her always drunk Godfather Hu Ba Dao, they were so funny when they worked together.
As for the story with Han Zheng I loved how him and Su Jiu Er were total polar opposites! She was always cold and he was warm, the same with their personalities. Anyway I felt like Su Jiu Er is sometimes too clumsy if you consider what job she has, which is a detective. I can't count how many times she fell, said something inappropriate and many more but I loved the personality of her. All the cases were interesting but the one I enjoyed the most was about one opera singer dying mysteriously.
The romance was slow but I enjoyed it so far. They were a perfect match for crime solving but for love as well. Even though Han Zheng didn't show his feelings towards Jiu Er that often I loved the jealous and caring him, he was so focused on saving his face when someone saw them together. But after this all things turned out in different directions because Han Zheng was wrongfully accused of killing Jiu Er's Godfather, but this issue got resolved in some episodes and I was happy to see Jiu Er gaining the trust in Han Zheng once more. I also think their relationship got stronger when Han Zheng got captured by Marquis Xian who was hunting for Qi people. I cried a little seeing them reunite after a while. I also loved how Han Zheng confessed his feelings to Jiu Er, I felt butterflies in my stomach. The ending satisfied me in a way. I was happy the three-scar man (Wen Ying) was sent to justice and our leads could be happily together, because they got married at the end!
Overall it was a great and fun watch! I liked the OST, I think the storyline could've been better sometimes but I loved the characters. I will miss them all!
