You are walking the streets of Seoul's city. You are tired and you were going home. You walk down on dark alley because it's closer to your house, but you hear some strange sounds. You saw a man drinking the blood of another man. The one drinking the blood was Yunsu. Yunsu Park is regarded as a holy man in the church you attend, but you just found out his secret identity. His lips are messy with blood stains as he drinks the man's blood.
