"You guys are so cute together! Although, I am curious as to why you were at Jin City for such a long time." Lu Yuqing wanted to know why Jiang Yao was away for an entire month.
News of Lu Xingzhi's injuries was withheld from his family because he did not want them to be worried, especially with how severely wounded he was. Since he was already recovering, there was no need to hide the news anymore.
As people mature, they get into the habit of only sharing the good news.
Lu Xingzhi felt that he was not a good son since he rarely returned home due to his military career. He would feel even worse if his parents got upset over his injury.
However, since Lu Yuqing asked, Jiang Yao did not feel the need to conceal the news.
