Title: The Sweetest Man
Minhoon and Hyungwoo have been best friends for 15 years. Minhoon has always been inexplicably drawn to Hyungwoo, but Hyungwoo has always had a wall up that Minhoon has never been able to cross. Yet, for some reason, Minhoon is desperate to do just that. One evening, after heavy drinking, Hyungwoo is in no state to take care of himself, and as he has always done, Minhoon makes it a point to take him and let him sleep at his house. What neither of them expects, though, is Hyungwoo to suddenly attack Minhoon, biting him on the lips in a sudden kiss.
At this point, Hyungwoo is forced to admit to Minhoon that he is actually a vampire, and due to the bite, Hyungwoo is now a kin – a partial vampire created as an immortal food source for their creator. A dark world is soon opened to Minhoon, one that is full of violence and danger, primarily because of Hyungwoo's father, the head vampire, who wants to take control of Minhoon so he can then control his runaway son Hyungwoo.
While Minhoon is struggling to come to terms with his new immortality, the threat of the surrounding vampires, and his daily life, he must also contend with something he has had to figure out for the last 15 years: what are his feelings for Hyungwoo?
