Luo Xuhua coming to pick them up was a coincidence, last night he happened to call, saying the project couldn't be finished immediately and that they should visit the Capital City when they had time. During their conversation, he learned that Luo Xudong and Beisitian were coming to Beijing.
The reason was naturally not easy to explain. Beisitian just said it was an acquaintance, an old gentleman who was ill, and she wanted to come over to see him. She's not familiar with the Capital City, so she brought Luo Xudong along.
This reason seemed reasonable enough, Luo Xuhua wouldn't overthink it.
"It's too late today, it's already past eight o'clock. Going anywhere now is inconvenient, wait until tomorrow and I'll take you guys over," Luo Xuhua said.
Just like what Luo Xuhua said, even if Beisitian couldn't hold back, she could only force herself to hold back.
