19th century England, an era when women's position was weak. The pastor's daughter, Leah, loved the world of stories from an early age and loved writing novels, but the men around her continued to deny that "a woman can't write a novel." At the age of 19, the work posted under the male name "Alan" is recognized, paving the way for a novelist. Then, dressed in men's clothing and heading alone to London, where the publisher is located, fate begins to move.
