"On weekdays? Who's going?" One day, his wife Tsumugi hands him a camping circular. Naturally, I said I couldn't go because of work, but Tsumugi, who is concerned about the eyes of the town and the women's association, seems to be willing to attend, even if it's just by herself. That night, when I sent my wife to see if there would be a large crowd, she was informed by email that there were only four people attending. She spends two nights and three days deep in the mountains, where the reception is poor and it is difficult to turn back... To make matters worse, she hears from people in the town that it is an unofficial event.
