Well, its already established that she is selfish and only think that she is in the novel that she can take it for granted. The way she react to the Prince abused proves that she did not think that the event is serious.
Yea, there’s often a way of distancing that happens when someone is transported to a world that they’ve read about or played through in a game. If the person was just transported to another world they knew nothing about they’d have far less knowledge about its world and people but would understand that everything is their reality…there may be no way to go back…and allow themselves to care more. She had convinced herself that Zerkan was a psycho at first, then like you said she saw the child abuse/neglect and tried to indirectly help him by appearing as an average child having outbursts or consoling him by using a flower that had to go through a lot but is still beautiful, she even gave him a jewel that fathers give their sons. I don’t think she would have tried so hard of not for the OGFL or her older bro, which makes me sad for Zerkan but he got a better life so at least there’s that.
She and her little agenda. I kinda love Zerkan more than her right now.
Like that everything is going smoothly, and at the same time I had a suspicion that the FL would think she could easily throw away all that married talk as soon as her older bro was in the clear. I hope it doesn’t take too long for her to realize that she either really likes or loves Zerkan separate from saving her older bro.
