I binge-watched this dorama the whole weekend. I can't believe I've never read nor see anything about this, the cast includes Fujiki Naohito and Kiritani Kenta! Fukada Kyoko and Endo Kenichi! Ishida Yuriko and Furuta Arata! The cover looks like a fun show. And the song is catchy. This kind of drama suits Fukada Kyoko so well. She is stunning, looks like a doll. Acts like a doll too, sometimes very wooden. And she loves to pout, but she does it so well! She is perfect for a simple-minded character. Recently I watched "Please love the useless me" (which was good, btw) and I said that Shunin was like Buchou, a little bit. And surprise! She has a dorama with Buchou, nonetheless. I liked the show, otherwise I wouldn't have finished it in a couple of days. It was light, as light as a dorama about cheating husbands can be. Kiritani Kenta runs an agency that investigates extra-marital affairs. Serina comes to work for him, and in the meantime, disguises herself to be close to her husband in his office. So while she is in disguise most of the times, it was pretty much the same outfit, not all the variety that shows in the poster, which was a bit disappointing. I hate love triangles, and even if the two guys are these 2 hotties, I couldn't like it. Besides, for the first time, I had a 2nd-lead-syndrome. Guy 1 is a jerk, does not appreciate Serina, takes her for granted, commits the biggest treason, does not deserve her love. Guy 2 has a lot more chemistry with her, is the only really likable character among punchable characters, and what is more, is not a jerk. And Serina... my, I wanted to shake her so badly many times through the drama. All she says is "Fumi-kun, Fumi-kun". She is very in love with her husband, to the point where she looks obsessed. She is the sweetest, but also a stupid, weak, and too forgivable. She does nothing. This is supposed to be the journey of a dependable woman that becomes stronger, but if stronger means turning right... (???) Every day she is watching her husband with his boss, flirting or not, sharing a mascot charm strap, etc, etc, and she does nothing except mope. Gawd, it was infuriating. Terrible ending. She does not change at all. Oh, and btw, her father is another big jerk! Can't recommend this to any feminist. The romance is super offensive. Taking aside that offensive fact, Serina in cover + some cases were amusing to watch.
