My Secret Vampire - Season 1

Strange country boy Dong-ha has been delivered to a bloodthirsty vampire house! Dong-ha, who lived in nature with his father all his life, is lonely. Dong-ha’s father’s last wish was for him to go to the city. Dong-ha passes the GED and moves to the city for university. Luckily, he finds a nice place where he can live if he donates his blood for research. His housemates, who are also his university department friends, even give him food and supplies. As Dong-ha gains more and more weight, his housemates start drooling. They are actually vampires, who are delighted that they found someone dumb enough to believe the world is full of nice people. But they are charmed by Dong-ha’s innocence, and when Dong -ha says he wants to pay them back in bed, they’re in way over their heads.
