Adapted from the Manhwa of the same name, "Kid Gang" is about the once most powerful crime organization in Korea. The 'Bloody Tuesday Gang' was entrusted with taking care of a baby by thier former leader six months before their parole ended. Ku Bong Son Chang Min was the leader with two other members Hong Lu Lee Jong Soo and Kal Nal Lee Ki Woo. This comedy focused on the task faced by the members who have to take care of the baby..

The story is about Su-han, a fatherly man in his mid-thirties, who becomes a full-time home manager after voluntary retirement, while his wife Mi-na becomes the breadwinner who had only concentrated on household chores up until then.

The subject of 'Bad Wife' is quite ordinary compared to other dramas. There is no amnesia nor is there an innocent child who contracts a fatal disease like other Korean dramas in the same time-slot. The changing roles of a husband and wife are not such an extraordinary or an unusual subject for a TV drama.

However, in such a banal setting, the drama succeeds in bringing out a variety of entertaining situations. By changing roles with each other, the married couple comes to face a new environment and, due to the new environment, they face changes through understanding and conflict. The drama realistically describes the process of such change, by providing a few details of some ordinary lives.

Min Kyung (Kim Hee Sun) just graduates high school and finishes paying off her father's gambling debt at a liquor restaurant. However, with some borrowed money, she runs away, promising herself that she will find a rich man and live happily ever after. Three years later, she is a stewardess at Asiana Airlines. She constantly looks at the materialistic objects any man has, judging everybody by what they are capable of buying. She meets two-three guys at a time while also attending blind dates with her co-workers. On one blind date, she falls in love with Young Ho (Go Su), thinking that he is one of the few people in the Yacht Club (a meeting of the few richest people in Korea). Young Ho is the son of a poor rice cake house, and works to pay off his dead father's debt. He falls in love with Min Kyung, because she looks exactly like his dead girlfriend. When Min Kyung finds out that Young Ho is not rich, she dumps him, and goes back to a rich man (Son Chang Min) who proposed to Min Kyung once before. However, Min Kyung wakes up to true love and realizes that happiness does not necessarily come in money.
