Before beginning with my review, let me give a summary of the story. As usual, the disclaimers first - if you do not wish to know the story, please skip this review as there will be many spoilers ahead.
One day, Sawa steals a bright red lipstick from her workplace out of impulse and happens to be seen by Takigawa Rikako (Kichise Michiko) who has just moved to Sawa's neighbourhood. That same afternoon. Rikako's car is vandalised by a senior high school student at the carpark near the supermarket thus resulting in both her and Sawa being called to the police for the investigation. This causes Rikako and Sawa to be bound by mutual secrets i.e. Rikako's affair with a younger man and Sawa's shoplifting. In addition, Sawa meets Kitano Yuichiro (Saito Takumi), the form teacher of the high school student involved in the case and the two of them strike up an unlikely friendship which gradually escalates into mutual attraction for each other. Despite Sawa's initial reluctance to go down the path of Rikako who tells her that having an affair can actually be beneficial to the marriage, she finds herself sinking further into the romance with Kitano who is also married to Noriko, an assistant professor older than him and is more concerned with her research rather than taking care of the household.
Story: 9.5 out of 10 (The unpredictable nature of the story created much excitement for viewers so that they could stay tuned right to the end. And that's precisely what's lacking in many dramas in recent years. )
Acting: 9 out of 10 (The ladies i.e. Ueto, Kichise and Ito all did well in their roles but the guys seemed under-explored so there was hardly anything to like or dislike about them especially Saito Takumi whose character's fate ended in such a disappointing manner.)
Theme song/BGM: 9 out of 10 (Nice BGM during critical scenes plus the catchy theme song which is hard to forget)
Visual effects / Scenery: 8 out 10 (There was some slow motion shots used to highlight the intensity of the emotions felt by the characters e.g. when Sawa almost burnt down the house and when she was in the forest with Kitano. The tension in the air was hard to miss and made the scenes more memorable.)
Teamwork / Chemistry: 7 out of 10 (Although Ueto and Saito are a nice combination to watch, I felt that Saito's character was too one-dimensional so it always felt that we knew how Sawa felt about him but his level of involvement in the relationship seemed unknown. Similar problem between Kichise and Kitamura where his side of the story is relatively unexplored. As such, the chemistry seemed to have suffered a bit. Contrary to this, the ladies seemed to enjoy better chemistry among themselves.)
Total: 42.5 out of 50
