Luo Qing is a bad woman. Everyone has always known that.
There have been no false accusations or slander. That's simply the truth, and even Luo Qing herself doesn't think she's a good person.
But so what? She doesn't care at all!
She's selfish by nature. If there's something she likes, she doesn't mind using any means to get it. As the saying goes, the ends justify the means. If it's something she wants, then as long as she gets it, why should she care how?
That goes for anything, of course, including people.
