Original plot is she ignores everyone because she assumes they arent real people and causes everything to go wrong because they couldnt sit by and let someone suffer.
The brother doesnt understand why she avoids him, the fiancee doesnt know why she took the fall when shes innocent, the villainess following the plot assuming the MC would stop her ruins everything cuz shes not stopped, her love interest cares about her and stopped liking his own sister cuz of what she did, the puppydog guy believed her lies, the King who raised her like his own daughter saw her get banished and hes definitely going to do this entire plot to get her back.
