Taking advantage of a long holiday break, my wife decided to visit her hometown via an overnight highway bus. We originally planned to go together, but due to my schedule, she had to leave alone. I watched her happily packing, excited about riding the highway bus for the first time, and said, "Well, take it easy and have a good rest." That night, I stayed in touch with her through a smartphone messaging app as she traveled... but then things took an unexpected turn.
