Jiuyue had great foresight in this matter. Before Duan Mingyuan set off on his business trip, she had admonished him that traveling alone, he might very well be targeted by those with ulterior motives. There could be people who would slip cards through the hotel room door, and she warned Duan Mingyuan not to trust these flyers, as they were very likely to be a "pitfall trap."
If he ever felt lonely and bored, he could video call her.
The company of a beautiful fox demon online would certainly be better than dealing with those women of unknown origin.
However, the current situation was a bit delicate.
Duan Mingyuan did indeed receive a card, but it wasn't an invitation for a romantic encounter. Rather, it invited him to explore the meaning of life. He read the card over again and found that the four questions it raised hit directly at the sore spot of office workers who had fallen into a state of ennui.
