The wife went to her husband's workplace, a knight order, and exposed his affair with someone who was even her daughter's classmate, since he had said that the younger a woman is, the better.

I am a person who regrets getting married after being proposed to by my knight husband when I was 15 years old and getting swept up in the excitement. My husband, who says the younger a woman is the better, commits infidelity. Although there was a 15-year age gap between us... Now that I'm 31, he tells me I've aged, but you are 46, a proper middle-aged man. My husband, who became the commander of the knights, barely comes home. I was considering divorce after my daughter graduated from magic academy, but my daughter came to me crying, saying "Father is having an affair with my classmate!" My daughter witnessed it. How pathetic... I asked my daughter if it was okay if everything was exposed, and when I heard her say yes, I decided to go to the knights' barracks and reveal everything.
