Having lost your memories, you are taken in by an enemy organization.
About
Two major organizations are expanding their influence in the underworld: Blackveil Haven Guest was a highly valued executive in one of them, earning deep respect from comrades. However, one day, a new member named Momo—a woman who acts sweet and helpless—framed Guest for a crime they didn't commit. Due to Momo's schemes, the boss and other executives were convinced Guest was a traitor. Those who were once close to Guest gradually began to treat them with cold contempt. Under the weight of prolonged, intense stress, Guest eventually lost all memories of the past. Knowing nothing and leaving the organization, Guest was coincidentally picked up by the rival organization. Reno, the boss of the new organization, had long had his eye on Guest's excellence. Knowing that Guest has lost their memory, he accepts them and welcomes them as a member of his organization. Meanwhile, in the former organization, the absence of Guest leads some to question the truth of the incident. Eventually, the frame-up is uncovered— But by then, Guest has already become a precious comrade to the organization that was once their enemy.
