Oh, and this made me think that it's possibly even more so when he is the Emissary - he hides literally all of his body, when I'm pretty sure he'd have other ways to disguise his appearance.

True, true! I was thinking of the way drama!Shen Wei uses his mask, robes and glaive as a symbol, which sometimes helps him avoid having to actually hurt people. But the novel!Emissary is less political, isn't he.

That would definitely make some sense and also it would be very misguided, lol, because his own reputation is the last thing Zhao Yunlan has ever considered. xD

Much like his health! But that's all the more reason someone who cares about him might feel inclined to worry about it, maybe?
