Romantic Egoist, also called Love Egoist, is a series of shōjo manga short stories by Bisco Hatori. "Romantic Egoist" is the title of the first story; the series title was changed to Love Egoist with the second story because, according to the author's notes, her editor thought the original was too long. So far four chapters have been included in releases of Ouran High School Host Club.
Each story is centered on a different couple's search for love, linked by the involvement of the Kuronuma sisters.
