The Curse of One Brother

Just as he was born, Youngmin was cursed to become a monster. Though he never realized it at first, he gradually came to notice how different he was from everyone else. How different he was from his friends. How different he was from his own brother. The sun hurt too much and the smell of garlic made him dizzy. Just the sight of something sharp that was made of wood put him on edge. Finally though, he found out just what he was when he started craving blood. His younger twin Kwangmin knows about Youngmin's curse and tries to help as much as he can. Since he knows that the older doesn't want to feed from strangers he let's him drink from him. What happens one day though, when Youngmin goes to far?
