As much as I loved this story, the writing in the first 15 chapters was so jumpy and didnt flow well at all. Then they finally figured out how to slow down and build suspense just to nuke the main villans plan before she even had time to do anything. THEN HERE COMES MIRROR BROTHER he had zero plans or a reason to come out of the mirror and it was never explained how he ended up there in the first place. OR why he has powers that have some how spread to the top 2 major families for generations. The only thing saving this is how strong the FL is and her relationship with the guild and Ray
After healing the holy knight and having her powers stabilize enough to heal the dragon why would she not immediately heal Ian?? She knew he would loose himself and become sick/ possibly die AND that he was highly dangerous just walking around under graces influence...
Plot.
Because she was mad at him which is dumb as hell. Like the other 2 male leads literally abandoned Grace after the brainwashing but she wants to act like they're all just naturally assholes that's why they hurt her.
Especially after grace broke the engagement they should've immediately gone to cure him. But nahhh Ian is apparently trash and a bad person for being too weak to resist ancient dark magic that has been poisoning him for months.
