The Monster King claims his favorite plaything after a long absence. For 1097 days and 14 hours, the protagonist has been confined to an asylum, haunted by dreams of monsters who worship her body. She endures the prescribed medication, which suppresses these visions and allows her release, only to discover that her dreams were not mere figments of her imagination. The Monster King and his demon horde were real, feeding on her desires, and now he has returned to reclaim her as their favorite plaything, a prospect she may be eager to embrace.

This novel is positioned within the popular Monster Romance subgenre, suggesting a narrative that explores intense, often dark, romantic and sexual relationships between human characters and monstrous beings. The premise, as presented, indicates a focus on themes of captivity, desire, and the supernatural, appealing to readers who enjoy darker romantic fantasy elements. The explicit mention of 'demon horde' and 'feeding off my lust' points towards a mature audience and potentially explicit content. The narrative structure appears to center on the protagonist's awakening to a hidden, supernatural reality and her subsequent entanglement with powerful, non-human entities.
