Ayase plays the lead character Isayama Nami who got married to a man on the spur of the moment after falling in love with him at first sight during a go-kon. Although she is a housewife who is living the good life in a quiet and upscale neighbourhood which is a huge contrast to when she was single, she is actually poor at cooking and cleaning the house and her biggest grouse is that she cannot stand her mundane life as a ordinary housewife. Nami also hates going around the bush and has a strong sense of justice which makes her extremely frightening when she is angered. She sets out to help the housewives living in the same neighbourhood who may look happy on the surface but have various issues hidden within. The reason why she is a thrill seeker will also be what she has been hiding from her husband and this will be gradually revealed as the story progresses.
With regard to playing a housewife for the first time, Ayase said that there will be some parts which will make viewers laugh but the action scenes when Nami punishes the baddies will be very exciting to watch so she hopes that everyone will enjoy watching this every week. Meanwhile, Kaneshiro said that this is the first time that he has a woman as the lead character in his drama which also incorporates elements of a home drama so it will be a big challenge to him. Nonetheless, he feels assured that Ayase is playing the lead role so he called upon everyone to look out for this drama.
To prepare for the action scenes, Ayase had been undergoing training in silat since June this year. Instead of relying on physical strength to overcome her opponents, Ayase will be using daily objects like cooking utensils, ballpoint pens and pencils as her weapons.
