The plot is generally good, but too many storylines remained unexplored. I hope they are spared for the further development in the second season (the drama ends on a cliffhanger).
The cast is amazing, each on their own and all together as a team. The bunny girl is not even irritating since she fits her character and there's a fair dose of mistery and maturity in her if you take a closer look. BTW, this has been my second drama where Xiao Zhan interacts with bunnies :-)
The production is horrible and negligent. Cringy set-ups and dialogs with nothing but turns of approving head shakings and tons of a very specific sound that means "yes" in Chinese :-). They get so bad at times that the scenes start before the actors start moving.
I'm surprised the MDL rating is so high. Not worth it.
