I am so happy I watched this drama! I had been holding it for a while because I wanted to watch it in a relaxed state of mind. It is a fairly refreshing drama. It has a very captivating plot and most of it fairly original. While exchanging of partners in movies not unheard of, this drama presents that concept in a whole new light. It has its shortcomings, but I think this show truly deserves a rating of 10. In some aspects, I can say this show comes close to being genius. Hats off to its writer because he wrote one of the most challenging stories involving romance that I have come across in quite a while. I can say that the first seven episodes were absolutely not predictable. I am generally very good at guessing things, but this show proved me wrong every time. Even after a certain 'twist' at the end of episode 7, I was pretty sure about the outcome of the story and even that left me in surprise. This is the reason why this show has very few dull moments. There is always something that you won't see coming in every episode that takes place that thoroughly makes you laugh. It is a rather bold drama compared to regular Jdramas with few scenes of intimacy. It would appeal to a more mature audience. Also, people tired of cliches should definitely go for it. This show has a good cast and the acting department was quite good. There were a couple of characters that came off as annoying- especially Usami but there were lots of other things that kept me occupied. Dynamics between all characters have been explored fully. The ending felt sort of forced, but even that ended up being funny. Every time a serious situation sprouts up, it eventually turns into comedy. It is a very lightweight drama. I loved the role of Matsuda Shota the best because his character was that of a playboy photographer. He carries out roles of bad boys pretty well. His female counterpart was ridiculous but I kind of fell for it too by the end. Also, the psychology involved in the story is pretty interesting. Almost every theory they put forward made sense and could not be argued against. The psychologist's character was a freaking genius. He very splendidly changed his shades from good to bad and back again. Airu was also a solid character among all females. Right from the scene where they all get stuck in the lift, she became my favourite. This drama has great comedy, good romance and great entertainment value. It makes you laugh without being too ridiculous, gives you romance without being cheesy and entertains you till the end. This is a highly recommended drama!
