@jmacena i'm just gonna guess this, but i think that affection maybe stems from the fact that the WMMAP is a reincarnation story, struggles of the princess in the original story were only mentioned in a third-person manner, and the MC didn't actually suffer through that hell herself. Also, adding to the fact that Claude's backstory was shown, which explained why he hated his own daughter- made the readers sympathise with Claude a bit.
Where as in this story's case, her struggles and her father's absolute lack of regard for her were shown RIGHT AFTER her unjust execution,
which btw made me cry a little lmao which made the readers sympathise with the MC's POV, and how immensely cathartic it was to watch her absolute disregard for her father and her resolve to live her life her own way right after she woke up after travelling back in time makes us hate him more. so yeah!
