i kind of wish that fl displayed more instinctive revulsion to the destitute/lower class that she has to overcome with effort, given how violently classist and ignorant she was pre-regression. it feels like post-regression her feeling of disillusionment just erased all the negative aspects of her personality instantly, which makes the "atonement" arc the author is going for feel a little forced since she's just a sweetheart now with hardly any character flaws
if i were writing this, i would change the scene with the lost child to have the child try and grab onto her, with fl batting the hand away or flinching out of instinct. she would then be overwhelmed by guilt for relapsing into her past life self even a little before consoling the child properly despite her lingering disgust, and then you could have the knight's inner perspective (wary because fl lashed out but then smiles slightly when he realises the effort she's putting in to change and be different from the rumors). it would have made for a nice scene to show her mental progress i think
yes they did have the scene with her mentioning the mother of an orphan, but that's an honest mistake and not really that indicative of fl's upbringing as a spoiled classist noble. she can't know the family circumstances of every child she sees on the street and anyone could have said that with good intentions
