Hyunjin belonged to the final generation of vampires known as Daywalkers - beings capable of walking under the sun without turning to ash. Living quietly among humans, his only concern was survival and keeping their kind hidden from the world. Cold and detached, as any vampire should be, Hyunjin's life took an unexpected turn when he crossed paths with Felix - a human far from ordinary. What began as an accidental encounter awakened something unfamiliar in his chest - a heartbeat that would soon lead him toward an inescapable danger.
