It's been five years since I married Hijiri, who was a colleague at the company. He is about to be promoted, and he has a good relationship with his wife, so much so that he goes to help his boss, Mr. Ozawa, who took care of him today, move. One day, a few days after moving in, Mr. Ozawa confided in me that he was having an affair with a married woman. I laughed at the usual joke, but he told me to show him the proof. When I went to the designated Japanese-style room, it was a magic mirror, and Hijiri, who should have gone out, came to the room on the other side.
