I went on a hot spring trip with a married woman I had just met. She works as a company receptionist, and her husband is a salesman from a client company. They decided to get married just two months after starting to date. As the second son of his family, he has a high income and intelligence, meeting all the ideal criteria for a spouse. Their relationship maintained a delicate balance—neither good nor bad—especially since he calls her every night from his business trips. Those frequent calls made her wonder if he already suspected her affair.
