Yoichi Haruno (Hiroshi Tamaki) is 35-years-old and works for a company. His wife, Chisato (Kana Kurashina), is 28-years-old. Before they had a child, their marriage life was easygoing. After having their child, their relationship changes. Yoichi feels that Chisato is cold to him, but he doesn't know why.

Smart, good-looking guy with an appealing personality, Haruno Yoichi thought himself as "perfect husband." However, ever since he and his wife had their first baby, he feels that his wife gives him less and less attention, but he can't figure out why or how to solve the problem. Soon the status of his existence at home has fallen to the level of good-for-nothing, "disappointing husband." His wife Chisato was polite, good-natured and always cheerful – a type of woman that anyone would view as "ideal Japanese wife." Then everything changed after the baby arrived. Now she easily gets irritated by Yoichi’s words and actions and often goes hysterical. Yoichi thinks Chisato somehow has turned into a "monster wife," so to speak. As Yoichi and Chisato face the "Postpartum Crisis" putting their marriage in jeopardy, how will they overcome their conflicts and save their relationship? Will they be able to grow together as husband and wife, as well as father and mother?
