At a university mixer, rural student Yuzu seeks a gentle, herbivore-type boyfriend. She's intensely drawn to Kaname, who sits quietly in the corner with a seemingly melancholic and safe aura. Believing him to be the ideal shy guy, she lets her guard down. However, in a startling turn of events, Kaname suddenly closes the distance and captures her lips in a searing kiss. The man before her now has a completely different, dominant, and predatory glint in his eyes—a stark contrast to the gentle man from just three seconds ago. This encounter marks the beginning of a dizzying romance where first impressions are dangerously deceptive. Yuzu finds herself entangled with a cool, metropolitan man who harbors a hidden, insatiable carnivorous nature.
