Guiyeoni (born 1985 in Jae Chun, South Korea) is the penname of Internet novelist Lee Yoon-sae. She first reached fame with her novels "He Was Cool" and "Romance of Their Own", which spawned commercially successful films of the same name. Since then, one of her other books, "Do Re Mi Fa So La Ti Do", has become a film starring Jang Geun Suk. A movie of "To My Boyfriend" is also in planning stages. Despite her commercial success, Guiyeoni has been criticized for her lack of literary perfection, overuse of emoticons, and unrealistic setting in her works. Also, there have been suspicions of plagiarism in her 2005 novel, "Outsider". Besides the aforementioned novels, she has also written "Africa", "Five Stars", and written and illustrated a manhwa called "Syndrome".
