A serial killer is on the loose in Seoul, countless young women have already fallen victim to him and the police have not the slightest clue. Jungkook falls into a deep depressive hole after his bloodlust, no matter how many girls he kills, it no longer gives him the same pleasure as it did at the beginning. But then a particularly interesting catch falls into his net. Jimin, on the other hand, has been in the asylum for years, alone in his padded cell and bored, missing the time when he used to kill everyone he had a one-night stand with. But then he unexpectedly manages to escape. Now two of the most dangerous killers of all time are on the loose. What will happen when sociopath meets psychopath? cover by @toni_ct10
