Yay Panda!!!
No... wait, that's another drama. A gem, by the by.

Skadoosh!!!
Still not the right one, my apologies.

Regardless of the motto, it seems that whenever a panda is involved, lots of fun is guaranteed. Granted, here the fun is quite dark. In the beginning you may even think this is a slapstick comedy/manga-like/action show that is going nowhere, but rest assured it is not and it does go to a lot of places without losing direction.
It has its frustrating moments and its plotholes, but they are easily overlooked and largely compensated by the story flow and the wonderful characters.

While Yokohama Ryusei is his usual smouldering and harrowing self, the star of this drama is without a doubt Seino Nana. She plays multiple roles and all of them are believable, extremely well acted and invariably adorable. If you're venturing into this as a fan of Ryusei, rest assured you won't be disappointed, but Nana outshines everyone here, both in acting as well as characterization.
The supporting cast is great too and I've lost count of the times I changed my opinion on Mr No Compliance and the unprincipled journalist. Miss Panda's mission is to clear the grey areas and reveal their black or white true nature, but by all odds this show is all about the grey. All the characters, including the leads, inhabit that grey area. Which is just fine: who wants to root for perfect heroes one could not in a million years identify with?

I truly loved the music. It complemented each scenes in a fantastic way, sometimes touching, often compelling.

As it often happens, this drama is seriously underrated.
Since there is a little panda-sense of justice in me too, I may have added that extra point to its rewatch value. Its "what will happen next" appraisal is clearly diminished on a second watch, but I can picture myself marathoning this a second time in the future, and enjoying it just as much.

Miss Panda!!!
It was a pleasure laughing with you.
