My wife Yukiko and I moved to this town last month. One day, she showed me a camp registration form that her student Kozawa Daisuke had given her because she works as an instructor. I wanted to decline since I have indoor work and other commitments, but my wife was eager to go camping so we decided she would attend alone. On the night of the camp, I received a call from my wife informing me that there were originally supposed to be more participants, but now there are only four people including herself. She promised to come back right away after the call ended...but the connection kept cutting out due to poor reception.

妻の有紀と先月、この町内に引っ越してきた。ある日、インストラクターとして働く有紀が生徒の小沢達から渡されたとキャンプの申込書を見せてきた。僕はインドアで仕事もあるので断りたかったが、妻はキャンプに乗り気だった為、1人で参加してもらう事にした。そしてキャンプ当日の夜、妻からの電話で全員参加の筈が参加者が4人しかいない事を知る。すぐ帰ってくるように伝えたが電波が悪いようで電話が途切れてしまって…。
