Riko is an ordinary office worker living an unremarkable life—until the day she suddenly finds herself lost in a world she has never seen before. There, she encounters a prince as beautiful and manly as a figure from a painting. Merely being near him sets her body aflame with an intense heat and ache unlike anything she has ever experienced. Though she knows it is shameful, Riko finds herself unable to resist seeking him out. Her body is consumed by a powerful estrus she cannot control, and she learns that the only way to suppress it is to have an alpha's essence poured deep inside her. As she is drawn further into this unfamiliar world, Riko must confront the meaning of being the King's Omega. What is this bond that binds her to the coldhearted prince, and why does fate seem to have chosen her alone? A tale of instinct and destiny unfolds in this authentic otherworldly omegaverse TL, where a ruthless alpha dotes on his one and only fated mate.
