Otto no Kanojo

It started with a misunderstanding. Komatsubara Hishiko suspects her husband, Mugitaro, to be having an affair with one of his young staff at the office. Thinking to confront the lady, Hishiko goes to her husband's office, but then something strange happened! Hishiko and the young lady, Yamagishi Hoshimi, swapped bodies. So, from a 39 year old housewife prone to anxiety attacks and day-dreaming, Hishiko is now a 20 year old Office Lady (OL). On the other hand, Hoshimi, who tends to speak her mind freely, finds herself in the role of wife and mother. In Hoshimi's body, Hishiko gets to see her husband at work for the first time and starts to appreciate and respect him. As she rediscovers her husband's charm points, will it help her to fall in love all over with him again?!
