Well...

Lily is super manipulative, silly, gullible. Lily gets her hopes up too quickly, she has no self-respect or self-esteem, she doesn't even know how to communicate well, or speak for herself. She seems like a little girl who has barely been touched and already thinks that's love, when she's just being taken advantage of for her beauty. She's so manageable that she's not even interesting.

I'm sticking around to read because Anna's character, despite everything, has dignity, and says her stuff up front to Lily and the Duchess. The Duchess is, as usual, just a manipulative, wealthy, pretty fuckgirl (like any male character in a manhwa).
