Kenji and Yuka have been married for 3 months but Kenji cannot spend much time with Yuka. Knowing that his brother had just divorced and had no place to live, Kenji decided to take him to his house to stay temporarily until he found a house. Yuka didn't want to, but Kenji, out of love for his brother, persuaded Yuka. At first Yuka was quite uncomfortable with her husband's loose personality, but gradually she found him quite approachable... and then they became closer and closer. Because she was so lonely after the divorce, her brother-in-law took over Yuka when her husband was not at home. But she gradually realized that it was her husband who could give her the ultimate happiness that her husband could not give her...
