I think since Lotus is seen as "Pure"-- when calling one "Black" Lotus, they're probably meaning that Minyue is... "An evil pretentious Dark hearted bitch who tries to act all "Pure" when she really isn't anything but rotten tramp!"

And if the host didn't transmigrate into Su Ziyue's body-- that dumbass Minyue would have ended up as the main lead--

So thank God the Host came to the rescue~(⌒▽⌒)
Thank you my friend.
I do love our host. She does tend to dish out nice vicious justice.
What's a black lotus lead?
