I think he just doesn’t know how to express his emotions and is just lashing out at him. I think he has feelings for Xin, but isn’t fully aware of it yet and there master and bodyguard relationship muddles things. So I think Lau is having a hard time because he doesn’t know what part of their friendship is genuine and what is just because of their roles of tradition and being master and servant.
Lau is so mean to him
