As the emperor's sister and presumptive heir, Elvia Violette Cecilia holds considerable power over the lives of many. She attracts numerous suitors due to her beauty and high status, yet on a whim, she might ruin an unwilling man's life just to force him into her bed. With a reputation for selfishness and a volatile temper, she is hated as much as she is loved. When a modern woman drowsily answers a phone call from an unknown number before falling unconscious, it is her great misfortune to awaken in the body of Princess Elvia.

There is a lot for Elvia to process in her new surroundings: she finds herself lying naked between two very attractive but unfamiliar men, and soon a text box appears describing the feelings and actions of certain people around her. Deducing that she has somehow fallen into a video game setting, Elvia discovers that someone else is also seeing the same notifications and making choices that affect the plot—and that other person is playing as the main character, whereas she is merely the villain standing in their way. If Elvia hopes to outwit her opponent and escape death, she must find trustworthy allies, even perhaps among the real princess' harem.
