Both feature a relationship between two women, one of whom is a bit insecure, and they both involve ghosts. Otherwise, they are very different. Legend of Yunze is a mystery adventure with some darker moment, while My Fairy Ghost has a more slice-of-life feel, following an author trying to write a book, and it is also more explicit about the romance. Both are short-length dramas with relatively simple plots that are heartwarming at times.
