Story :
The background, the conflict even the reveal of each secrets is really superb! I love the slightly plot twisting in this series, but really I dislike the ending T^T

Acting/Cast :
You don't have to ask me this, Ikuta Toma, Oguri Shun and Ueno Juri in one frame? It's like heaven on earth! Their acting are superb, dazzling and badass at the same time.

Music:
Honestly I forgot about the detail of the music, what I remember is the music really fit the series.

Rewatch Value:
Definitely will rewatch this to find any detail I might be missing in the first place because I'm too busy to fangirling. LOL.
