No Way, Vampires Don't Exist!

Four college housemates — Ju-Won, Eun-Ho, Seon-Jae, and Gyu-Min — are in desperate need of a fifth person to fill a vacant room in their place. But their main concern isn’t about paying rent: they’re ravenous vampires, dying to sink their teeth into a fresh, live human! So they can’t believe their luck when Dong-Ha, who grew up isolated from society, eagerly moves in with no idea of what awaits him. To the vampires’ dismay, however, Dong-Ha doesn’t weigh enough for them to suck his blood! As they shower their unsuspecting new housemate with food and attention to fatten him up, have they gotten too attached to their would-be prey? And is there more to sweet, naive Dong-Ha than meets the hungry vampires’ eyes?
