I understand the Ceo,setting and stuff.. but personally for the FL I'd choose author-nim. He at least likes her(admits it to himself at least), makes an effort and is interested in here fairly
The Ceo guy didn't like her- was mean to everyone AND her, up until the middle still was mean and is only caring about her now that he starts to like her. It's not his personality, just circumstances that makes him treat her like a person. He wouldn't otherwise.
-and coming from a woman with a relationship score! The one you see before they like you is the one you see once they lose interest.
So treatment-wise, author's a winner in my opinion.

I was understanding her at first, understanding her circumstances for both of her lives and how much she's insecure, but girl, after the debutante part....BRO YOU CAN'T LIVE TWO LIVES AND STILL BE A PUSHOVER! She needs another life to heal those insecurities, wtf are you a doormat? They already told you that you're a family, you accept it, yet you get pushed around by some countess or whatever in your own house? With the maid disrespecting you?(you're a part of a family still?) The fuck? She should have at least fired the servants but no. Ok. Dunno. I dislike this type of characters a bit, they don't change. She's the same way she was in her first life. Not love from her new family not anything changed her(enviroment change, peace and love for a prolonged period of time heals some trauma, so we could assume it as a type of therapy for her). But still she has no character development. Not interesting. At this point it's not even her mental state but her choice. She wants to be a pushover. Or a naive sunflower, name it yourself
I actually want to read about an isekaied therpist to different novels, and how they help change the heroines to accept reality and themselves. That would be an interesting read
