Thrill of Adventure

Much different from her mother, Y/n loves going on adventures and solving mysteries. One day, at age 17, she finds a book while looking through her mother's things.
She was warned about it but didn't listen. Reading it wasn't a problem but being naive caused this young lady to cause a big problem for herself.
A year after, at 18, she foolishly wishes for something that she never thought will actually happen.
