Half an hour before the ball was all free activity. Lu Shaoyue brought Ye Shuang around the cruise, and they basically spent that half an hour greeting people that came from all walks of life. Some they knew, others they did not.
It was naturally Zuo Yuanhang and his wife who had the first dance. After the host stepped onto the dance floor, those that dance partners also joined them. Lu Shaoyue had a dance with Ye Shuang, and after that, it was time for people to change dance partners and interact with the other guests.
Ye Shuang and Lu Shaoyue were not in a relationship, so of course, they did not have to stay at each other's side—they only needed to show up and leave together. Therefore, as they parted from each other, Lu Shaoyue was dragged away from one of the other guests, and Zuo Yuanhang's assistant came over to invite Ye Shuang.
