Momoko Ijuin, after graduating from a junior college and completing two years of bridal training, married Kouji Suzuki, her childhood fiancé arranged by her parents. Both of them were 27 years old this year and had been married for five years. One day, her husband unexpectedly asked for a divorce. When she inquired why, he admitted to having feelings for another woman, who turned out to be his former lover. After a chance reunion with this woman, his feelings reignited, leading Momoko to agree to the divorce. She made this decision considering his strange behavior over the past six months and his increasingly rare returns home over the past month, realizing that continuing their marriage would be difficult. Kouji, having finally married the woman he loved most, was at the peak of happiness. Therefore, he failed to realize why Momoko agreed so readily to the divorce.
