After being married for three years, although we don't have children yet, my husband and I have been living a happy life together. One day, my wife asked, "It seems there's a company retreat coming up. Can I go?" I nodded happily. However, when my wife returned from the retreat, she was dressed differently and more neatly than usual, and I felt a sense of unease and discomfort towards her. Feeling troubled, I decided to play a video from an unfamiliar camera in her bag... I inadvertently opened Pandora's box.
