A reader is magically transported into a BL novel called The Night of Hwangseong. She now inhabits the body of Lobelia Flore, the daughter of a noble family suffering from a rare illness. Lobelia discovers that the only way to avoid a painful death is to keep in close physical contact with Edric Dencart, the young, beautiful, and sickly son of The Duke of Dencart. To do this, Lobelia disguises herself as a man named “Lobel” and commits herself to becoming Edric Dencart's most trusted manservant.
