i happened to be on a business trip... my wife travels to kurokawa onsen with an unknown man.

Four years after I married Sumire, I had no children but lived happily. Sumire supported me as a full-time housewife, and my work was well done, so I decided to go on a business trip for three days because of the big contract. On the first day of my business trip, I went back to the inn after a business meeting and felt unbelievably anxious about his wife's appearance and voice, and when I looked into the room where a woman similar to his wife entered, my wife began to kiss a strange man. Even though I was attacked by intense anger and despair, my eyes couldn't help but lose their appearance.
