Yumi and I got married after a workplace romance, and several years have passed since then. Today, we went together to help our close colleague Yoshimura move. Concerned that he was still single, I advised him to find a girlfriend, but he refused to listen and instead confessed to me that he was having an affair with a married woman. Since I thought such a thing was impossible, I demanded proof and confronted him at his place—only to witness a shockingly disturbing scene far beyond my expectations.
