Marui is an up-and-coming corporate worker, but his climb up the corporate ladder has been blocked by another man: Ryougo. Ryougo's smart, efficient, hard working and well connected, and there's simply no way Marui can go over him. Until one day he discovers a website allowing him to modify a single person. He chooses Ryougo, of course. Now renamed Ryouko, she's a bit slow and clumsy low ranking office worker with no hope of promotion. She's also masochistic, horny, kinky in bed and most importantly, Marui's newlywed wife. The only problem: Ryouko still retains her old memories. But for how long?
