Before I go into details about her performance and how this drama fared in my opinion, I would like to give a brief recap of the storyline. In case you haven't seen this drama and would not want to know how the story progressed and ended, it might be best for you to skip this review.
Subsequently, Asumi received a copy of her father's surgical records from an anonymous person where the details on the form were different from the copy she had received when her father died. This suggested that someone had amended the original surgical record and provided Asumi the falsified version so that she would not suspect a thing about her father's death. Given the details on the original form, Asumi was convinced that someone was behind her father's untimely death so she changed her surname by becoming the foster daughter of her father's friend Mizuno Kazufumi in order to infiltrate the university hospital and find the true culprit.
However, the cover is blown soon and Nishikado, upon knowing that Asumi is back at the hospital to investigate her father's case and take revenge, tries to talk her out of it. He also apologises for having misunderstood Takao back then and wrote an incriminating article against the latter after his death because he was apparently misled by someone then. Blinded by fury under the assumption that Takao's crime sort of led to his sister's death, Nishikado then wrote that heavily-opinionated article against Takao without doing his due checks. Much as Asumi hates Nishikado for having a hand in smearing her father's name and sort of taking the side of the baddies, the animosity between them is quickly gone as Nishikado promises to help her since he knows that he cannot talk her out of her revenge plans. Nonetheless, Asumi still doesn't trust Nishikado fully in the beginning especially as he is critical of her methods in taking revenge.
Talking about the ending, I think I felt the same way as I did when I watched "Koori no Sekai". How can someone who completely slipped under the radar and had no links to the case at all suddenly show up to be the evil mastermind? What's more, he didn't set out to be the baddie but simply became one due to his unintended action? Although it was quite apparent that this person could be the possible mastermind after pretty much everyone was dead or eliminated during this revenge process, it just didn't occur to me on how he could have fitted in the whole equation. As such, it felt a bit like a hard-sell to make this character the ultimate mastermind and is barely convincing when Asumi simply forgave him because he went to surrender himself to the police.
As for the romantic side of things, I sort of expected that Asumi and Nishikado would not be able to get together, at least not at the end of this drama. Somehow, a lot of dramas these days tend to steer clear of very explicit endings where the male and female leads would end up together as a romantic couple especially since their interactions so far have been nothing but romantic. Having gone through the rollercoaster ride of taking revenge, it will probably take some time for them to come to terms to what had happened and get back to the normal state of things before they consider romance between them as a possibility. Well, that is something which viewers can only imagine and not get to see by the end of the drama.
Story: 6 out of 10 (The last few episodes of the drama seemed to be in too much of a hurry to wrap things up that quality was uneven and I didn't like how the ultimate mastermind was crafted into the story. Using "Alice in Wonderland" as a reference in certain points of the story was not really necessary, in my opinion. This reminded me too much of "Maou" which used a similar method to warn people of their impending deaths.)
Acting: 7 out of 10 (Ueno Juri had the potential to go full out as a dark heroine but too bad the story wanted to keep her firmly grounded as a dark heroine with an humane side so she couldn't go all out with the coldness and cruelness caused by her circumstances. The remaining cast members performed credibly but nobody really stood out. Odagiri Jo was so bland in this drama after episode 3.)
Theme song/BGM: 8 out of 10 (I thought that the theme song was quite good and very easy to remember after listening to it a couple of times. BGM didn't leave as much of an impression on me.)
Visual effects / Scenery: 5 out 10 (Most of the scenes were confined within the hospital but there were some nice sakura scenes in the first few episodes.)
Teamwork / Chemistry: 5 out of 10 (Not much chemistry as far as I see. Ueno and Odagiri's characters were not really comrades in war nor lovers so there was limited opportunity for them to show great teamwork or chemistry.)
Total: 31 out of 50
