I gotta say lads , this is pretty much a f*cked up mess involving a woman who's trying to figure out who her husband's murder is. Shes known to not have committed the crime and yet, she is put into jail. Pretty much society turns their back on her. She later joins a crew of serial killers who are Paul, Boom and Ms Box in order to take revenge on those who killed her husband. Paul and Boom pretty much have messed up backgrounds which involved the adults in their lives treating them like crap. You really get a feel for each characters on why theykill in the first place. This story guys is not for the faint hearted and like it is definitely gory so yall been warned. I do wish this story wasn't split into 2 seasons since season 2 hasn't been announced yet. Oh well this manhwa is a really good story to check out if you like your revenge manga. It's also NOT FOR KIDS!
