Ascendance of a Bookworm Part 3 Story
After a bad incident with a noble, Myne finally decided to part ways with her family and friends in the lower city. She changed her name to Rozemyne and started a new life as the adopted daughter of the archduke of Ehrenfest.
Rozemyne's new life in noble society has not been easy. She had to undergo rigorous training in etiquette and magic, while still performing her duties as High Bishop and forewoman.
All that responsibility was a huge burden for a seven-year-old with a weak body. However, the High Priest later offered access to the temple's book room as a reward.
With this opportunity, Rozemyne was able to read more precious books. Although her name had changed, Rozemyne's passion for books remained the same as she entered a new world.
