Olivia, who had just turned eighteen, was transported to London in the 1990s. She lived an ordinary life in a convent until one day when she was eleven, a letter and a person changed everything. She turned out to be a wizard? Olivia got on the train bound for another world in a daze and started a new life.
Demining: The characters should be as close to the original work as possible, and not to discredit everyone. The only golden finger of the heroine is that she knows the plot (but I don't know the plot in detail). I am not sure if there is a male protagonist, there may be no cp, and the female protagonist has a growth type (mainly I want to write about an ordinary person, so the female protagonist will be soft-hearted and scared, not a perfect heroine)
