A betrothed couple switch bodies in the throes of passion just two days before their wedding. There's nothing for it but to go ahead and get married... Each takes on the identity and life of the other. Ginko goes to work in Kameido's office -- and soon finds herself fending off the advances of cute OLs and trying to hold her own in afterwork business parties. The former man, meanwhile, takes on the duties of a housewife -- and discovers to his surprise that he enjoys the domestic life of ironing, cooking, and shopping.
