One day after work, my wife Fumino tells me about a camping trip organized by the neighborhood association. For some reason, it's held on a weekday and lasts for three days and two nights... Naturally, I wasn't planning on letting my wife go because I couldn't attend due to work, but she was worried about what the women's association would think, so she said she would go alone. I allowed her to go if there were a lot of people, but on the day of the camping trip, she tells me that there are only four people participating. I grew worried and hoped that she would come back safely, but contrary to my feelings, she became the prey of middle-aged men...
