My wife Mio and I are approaching our third wedding anniversary. She had been a full-time homemaker, but boredom and the upcoming anniversary made her want a part-time job. Hoping to support her, I introduced her to a factory where my friend worked and where extra staff were needed. She was hired without trouble, and we were supposed to enjoy a happy anniversary. What I never imagined was what might happen when one woman was placed in a workplace full of men.
