Chuuya Nakahara thought he had left the Port Mafia-and the pain of his past-behind him for good. But when an unforeseen threat forces him to return, he finds himself once again entangled with his former partner, Osamu Dazai. Under the guise of a reluctant alliance, Dazai brings Chuuya and a new team of young recruits into the Port Mafia, claiming it's for their safety. But the deeper they work together, the more Chuuya realizes that Dazai has more than business on his mind-and perhaps Chuuya has been carrying feelings he never expected, even after all these years. In a world where loyalty and betrayal blur together, can two broken souls truly find redemption in each other? Or are they destined to remain bound by shadows and light?
