Kim Jaesu had never been given a choice with his path in life. Forced into a life of crime by his uncle, he's finally made it to the very top of the Korean Underworld as the leader of the Syndicate, one of the Big Five criminal organizations in South Korea.
But as he's found his place in society, a new group threatens to overthrow that place, infiltrating South Korea and Japan with intent to kill and win. And it isn't just killing gang members and buying property. They seem to have another nefarious agenda.
Jung Joonho is known throughout the country by two different monikers - the CEO of Jung Industries, a multibillion dollar coorporation, and the Demon. Since childhood, he has been at Jaesu's side, as his only friend, his right hand man, his lover. Joonho is unable to process emotions, and even if he told Jaesu he didn't love him, he has remained beside Jaesu with no intent to leave him.
This is the story of two men as they battle their way through the dregs and highs of society, the family they've formed, and their unhealthy, possessive relationship with each other. Because Joonho is exactly his namesake, an unfeeling killing machine, and Jaesu is just formidable, with his history of how he rose to the top of the Syndicate.
This is a M/M dark romance, focusing on both the past and present, and their somehow happily formed family, with unhealthy coping mechanisms and relationships.
