The wife was approached by a stranger while traveling with her friend. (Fujii Yochi ADN-460)

My wife was invited by her friend Adachi to a hot spring trip. I was actually quite worried, but I've been very busy with work lately and haven't been able to take her out... I reminded her to keep in touch, and then saw her off. That evening, I called my wife, and it sounded like she and Adachi were both drunk... Hearing her hang up the phone in a panic made me uneasy... ...After that, I couldn't reach my wife anymore.
