The purpose of Yurong's call was simply to tell him she wouldn't be coming back for dinner, and perhaps not even tonight. This was very unusual for Yurong unless she was on a business trip out of town. Li Yan knew she had only left in the afternoon, so he asked where she was. She hesitated a bit before saying she was at the Prince Hotel and that something had happened, requiring her presence to handle it.
If she had some social engagement or was there for fun, Li Yan wouldn't think much of it, but mentioning something had happened made him curious. Because the Prince Hotel, located in the outskirts, was an investment of the Paradise Group. It had a professional hotel management team, and even if there were major issues, it wouldn't need the group president to handle them. Besides, from what she said, the matter couldn't be resolved even tonight.
This made it even more unusual. It was likely an unexpected emergency and very serious, even beyond Yurong's expectations!
