I like Nanyun Xun very much. This is Xunwen. If you don't like it, don't read it. CP should be the young master.
I will try my best not to slander Yukimura Chizuru... (Although I really want to slander her = =)
In my mind, Xun is a child with a twisted personality who is only gentle to Chizuru, so Xun is not white.
That's pretty much it, I really don't know anything about copywriting…
