Two years ago, I married Yuria Sasahara. She used to work as a narrator, but after marriage, she took a break from her career to focus on housework and childcare. To help support the household financially, she decided to start taking English lessons as a part-time job. One day, I passed by a black man near my house and felt slightly uneasy, but I ignored it and returned home. However, when I got back, I noticed two cups on the table. Curious, I asked my wife about it, and she confessed she had been practicing English with her black male instructor. I was shocked to realize she had been inviting this black man into our home without my knowledge. Everything I had been unaware of until now hit me like a thunderbolt, and a deep sense of anxiety began to grow inside me.
