Plot
Eun-Jae (Choi Ji-woo) and Hyung-Woo (Yoon Sang-hyun) have been married for one year. They are both lawyers.

They first met at a baseball game when they happened to have seats next to each other. During the baseball game they kissed and fell in love. Hyung-Woo told Eun-Jae that he wants to become a human rights lawyer. Eun-Jae supports his dream and they opened their own law firm together.

One year later, the thrill is gone in their relationship. Eun-Jae struggles to maintain the law firm alone, while Hyung-Woo helps clients who are not able to pay much for his services. Their interests have also diverged. One day, the couple learns that Eun-Jae did not register their marriage. The next day, Eun-Jae goes to file the proper papers. Eun-Jae is unhappy that Hyung-Woo is so generous to others and wants him to think about her more. Later on, Hyung-Woo's friends, who are a couple, stops by the law firm and the wife, Young-Joo (Jo Mi-ryung) insists that she wants a divorce. Young-Joo states that her husband Ki-Chan (Kim Jung-tae) hasn't worked in years and, yet, still gave his family a large sum of money. The married couple start yelling at each other. Ki-Chan states that he borrowed the money from Hyung-Woo.

Meanwhile, Eun-Jae hears of the loan and has had enough. Eun-Jae decides that they need a serious talk. Eun-Jae and Hyung-Woo then book a trip to Japan where they had their honeymoon.

When Hyung-Woo and Eun-Jae arrive at the airport they find Hyung-Woo's mother there as well, believing she was invited to their trip to Japan. Making matters worse Hyung-Woo receives a phone call from his mother-in-law asking to see him immediately and to keep it a secret.
