As for Lun Ying's feelings towards Weihuan, Gui Xi has maintained the same attitude over the years, which has never changed.
First, he doesn't think Weihuan is suitable for Lun Ying. Second, he doesn't believe Lun Ying could smoothly end up with Weihuan. Finally, even if they overcome various entanglements and get together, he doesn't think Weihuan could protect Lun Ying for a lifetime.
Lun Ying's background cannot be described as pitiful, but at least it is lamentable. She has no father or mother, has been independent and strong since childhood, and her nature tends to be cold. Someone like her actually needs someone who can give her familial warmth and understand her inner chill, which Weihuan's family cannot provide, and neither can Weihuan!
As for Chen Wei. Gui Xi sighed; if he could truly move Lun Ying's heart and provide her with some reliance, he would, in fact, be happy to see it!
