So the magic exclusive to the royal family also makes them instinctively love each other, so when the redhead princess stole her magic, she also took her chance to be instinctively loved AND was making them love her instead. That kind of explains how they adored her in the novel timeline even though she's not a good person vs not even liking her now.
Still, she (MC) noticed the father/king must have known she was the real daughter in the original timeline, yet was still rejected. Even if her magic was completely drained, he could tell it was hers. I don't see how can one redeem from that, even if I feel sorry for him rn.
Only reason I call it a “redemption arc” is because he didn’t do any of that this go round. He hasn’t even had the time to. I’d get treating someone like that whos already done that, but this is a completely new life from the other. She’s also recognized that it is and that the course of the story is changing. In this timeline, there’s really nothing to redeem from. This is probably what would happen had the consorts daughter not stolen her magic, and the consort manipulating them in the first place.

Has anyone heard of a redemption arc or…? I believe they just gave up after not finding the child for so long and having no hints to her wherabouts. They were not only being manipulated by believing the child was a dead son, but the consort was also utilizing magic. Obv if time regresses they wouldnt feel the same. The story hasnt regressed to that point. Not all fantasy stories are linear and i believe it adds better plot?? Its interesting.
