Tanaka Rena plays the mistress of her boss in Utsukushiki Wana who is old enough to be her dad. I can't remember the last time I saw a good Tanaka Rena show. Maybe Ganbatte Ikkimashoi? Anyway, wifey knows about Tanaka Rena and so she sets Tanaka Rena up with her lover who has a thing for older women in a 'I know what's going on and I want you to stop' act without actually saying she knows.
Husband of course gets the hint and pulls out and Tanaka Rena responds to wifey's challenge by going along with the set up instead of choosing to back away. Lover boy who can't get the wife to leave the boss decides to play along and we have a good girl mistress vs scheming wife story.
Bframe recommended Utsukushiki Wana to me with saying that the show is so bad it might be good and it is pretty bad in the afternoon soap opera kind of way. While Hirugao was a tacky drama that tried to be something serious, Utsukushiki Wana revels in its tackiness. The acting is unbashfully bad that its kind of fun, at least for the first two episodes.
The problem is that the main character Tanaka Rena is playing is too nice. I want more backstabbing and manipulation but that character never really dips her toes into that area. First two episodes were interesting but I ended up skimming 3 to 5 waiting for her to do something. Watchable if you like Tanaka Rena and/or you want something soapie. For me the heroine is too nice which is standard for these type of shows and none of the characters are that interesting.
