When you are not in love, you may just be a passerby who won’t look much at it, but when you really fall in love, you want to give the best to the other person. This is the case for Yao Ji, Murong Jue and Wen
The same goes for people leaving.
As for Xuanyuan Beichen and Qiu Huang, Yao Ji doesn't know what they are thinking and doesn't care. No matter how you look at it, these two are rivals and not friends, and their relationship is not closer than that of Wen Renli, at least Wen Renli is.
