For Baekyoung, being a succubus isn't as glamorous as the stories make it seem. It's her tenth day on the job, and she is absolutely famished. With her high standards for a "gourmet meal" crumbling under the weight of her hunger, she spots a target of convenience: Kang Chu Bong. He is the definition of mundane—a meek, glasses-wearing salaryman in a boring suit who looks like he wouldn't know passion if it hit him in the face. Desperate for sustenance, Baekyoung decides he will have to do for a quick snack.
But as soon as she takes a bite, everything changes. Beneath Chu Bong's nerdy exterior lies an energy so rich and addictive that it completely overwhelms her senses. What was supposed to be a one-time meal turns into an obsession, as Baekyoung realizes she has stumbled upon a rare delicacy she never expected to find in such a plain package. Now, the predator has become the one hooked, and she is determined to make this unsuspecting office worker her personal feast, no matter what it takes.
