I was excited when I first heard about this drama. Then, I watched the first episode and I think that it is okay. Not great but it is worth to try and watch it till the end. But after half of the second episode, I was done. I don't have issues about all the sexual innuendos or how the drama is a bit more 'daring' than the usual Japanese dramas. The problem was the whole 'stupidity' - and I am using the word loosely here. Sho was right when he said that the relationships in this drama is complex. I got it. That Saeko is a bitch or more to a slut in here - on how she kept being with new men or how she is attracted to Souta despite being a newlywed or how she cheated on him with her so called ex-boyfriend. Ishihara Satomi is doing great in making people hate her character and I applause her for that. But if I keep on watching it, I might get a high blood pressure because of Saeko and Souta's behavior.
The writers might go for something like a true and sacred love here but I don't see the 'sacred' love here. All I see are a stupid guy who is foolishly and blindly in love with a girl who had broken his heart and that's definitely not my cup of tea. So yeah, I might drop this drama after this.
p/s: This is the reason I prefer watching some detective/crime series of comedy. They are less stressful.
