Vampire Heart

On the night of a full moon, Dokyung runs into a vampire with blood dripping from the corners of his mouth. Haunted by the encounter, he tries to dismiss it as a dream...but not only does the vampire go to the same school as him, he begins following him around everywhere! Dokyung is horrified of course, but as time passes, he discovers some peculiar quirks about the creature: he prefers his meat well done, flinches at the sight of cats, and loves to cuddle. Who is this mysterious vampire, and why is he so fixated on Dokyung? (Source: Lezhin)
