I can understand Bertia, winning heroine in vast majority of stories is an epitome of care and patch up whatever misery mc got through with an "obstacle" as villainess shenanigans, but this time she is using her knowledge to undone or prevent things that would happen.
I like that Cecil isn't bathing in the glory, he operates "in the shadows", this would be suspicious if he had the knowledge of epidemic and be prepared before an outbreak could claim more lives, same thing happened during COVID after all, as people grew suspicious that vaccine was created in such short time, seeding doubt it wasn't man made to cause trouble.
Looking forward to Bertia trying to steer the story on the right track, but winning in the end.
Also, that's a red herring with the amulet if I ever seen one...
