Liang Xun was not young anymore. He was Liang Wei's eldest grandson, and his uncle Liang Yong was nearing fifty. Liang Xun himself was over thirty, an age of maturity and stability.
In comparison, Mu Jiangli is only in his twenties, and there probably hasn't been much interaction between him and the older members of the Liang family.
Therefore, Mu Jiangli's background remains mysterious.
"He has a clear background, but his attitude is quite strange. I've suspected if he might be... one of our relatives, someone who changed their name and identity. But..." Liu Shimei sighed and said, "I've tried to inquire several times, but he never wanted to talk about it. He's very tight-lipped. I think, as long as he refuses to talk, we probably won't find out anything, right?"
