Summary
During his youth, before Kai Chisaki was called Overhaul, he accompanied his boss to a meeting with another crime syndicate as his right-hand man. However, during that meeting, a single shot pierced the head of the other syndicate leader, killing him. Even as the assassin escaped, Kai was able to follow her, and without her knowledge, caught a glimpse of her face. And at that moment, Kai Chisaki fell hard for the mysterious killer known as Lady Nagant.
An OverNagant fanfiction in which I do not have to worry about all the nuances of canon Kai Chisaki, specifically, his much darker morality. I have only written one fanfiction before, so be prepared.
