In Itaewon, there is a very popular unnamed restaurant assumed to have a taste that no human can make. Hong Ki Joon, the owner and chef, is not really a human! He is a half-vampire born from a human father and a vampire mother. With his unique vampiric senses, he makes out-of-this world flavors unobtainable by man. But for him, there's only one thing! He can't imitate the taste of a heavenly drink... the blood he tasted on the lips of his kindergarten friend! Suddenly, his childhood friend, Kang Miro, anxiously appeared in front of him after 25 years. Now a 30-year-old office worker who's tired as a bee, her delicious blood is covered with the stink of cigarette, alcohol, fast food and MSG!
