I love this kind of story (the FL isn't weak, she's just been incredibly abused, manipulated, misled and belitttled her ENTIRE life Have patience, her character is progressing! ) and the art is gorgeous & incredibly detailed.
So...I kept reading, even though sometimes the translations were intelligible
Thank goodness for the 'better quality' uploads from @AkumaKira! Honestly without you I'd have dropped this, cos the previous uploads were painful to read (forgive me previous upload, grateful for the uploads...Just wish I could understand them ).
All hail AkumaKira!
