After having read the manga, I started watching this drama with high expectations. And well, maybe they were too high. The whole idea of switching between the "ON" and "OFF" modes is already good itself, but unfortunately it's not used well in this drama. Yes, we see Nika in her "OFF" mode sometimes, but most of the time she's in her "ON" mode trying to hide her true identity. So in the end, the plot isn't so great. We only get to see some stupid and irrational situations mixed with the "romance" between Arata and Nika. Because can we really call it a "romance"? They fall for each other so randomly that it's just hard and painful to watch. For example, only one friendly smile from Arata is enough to make Nika fall in love with the guy, and vice versa. Their relationship is just ridiculous. Nika is kind of annoying and has a strong sense of justice, as almost every character in Japanese dramas/animes/mangas. Although I don't know which Nika is more annoying, the one in the "ON" or the "OFF" mode. Nika in her "ON" mode tries so hard to be perfect and flawless, which is irritating. On the other hand, Nika's true self acts as if farting and getting rid of unwanted body hair is something forbidden, unnatural. Really now? Then I must be some kind of a monster since I fart when I'm alone, I shave unwanted body hair, and I don't want the product I bought to waste so I cut the package open to use what's left in it. Also, her "OFF" mode isn't even that bad. She just tends to dress herself weirdly. And her hairstyle is ugly. As for the acting, I really couldn't stand Nishiuchi Mariya's. Her facial expressions were odd, her way of talking was annoying, and her body gestures were just ridiculous. Fortunately, Arata isn't as annoying as Nika, but he seriously needs to stop with his "two personalities" thing. One day he's nice and sweet, only to switch to his "I'm a cold guy" mode the next day. And he's a really oh-so-great-and-caring boyfriend considering he does nothing when the situation between Nika and the evil teacher occurs. You have a great taste in men, Nika. Also, I don't find Kiriyama Ren's acting that amazing. Overall, it's not a long drama, so if you have some free time to spare, are really bored and aren't afraid of Nishiuchi Mariya's bad acting skills, you may want to give this drama a chance. Who knows, maybe you'll like it more than I did?
