I Became the Emperor’s Sleeping Pill

I’ve been transmigrated into the world of a dark, R-19 omegaverse novel. In this world, emperors—all of whom are incredibly dominant alphas—suffer from crippling insomnia. To combat this, they keep betas, known as Nyxna, by their side, drawn to their calming, human scent. But I haven’t just been transmigrated into any role; I’m now an extra, an omega concealing her true nature while serving as a Nyxna, who gets caught by the Empress and brutally killed.

After agonizing over my predicament, I hatch a plan: use the emperor’s desperately sought-after mother’s urn as leverage to save my life. The problem? The emperor, the main love interest, and even the sub-male lead are breathtakingly handsome. Well, since I’m here, I might as well experience each of them before escaping the palace…

Except, reality is starting to deviate from the original story. Will I even make it out alive? I’ve become the emperor’s sleeping pill!
