Tides of Fate

In this Omegaverse AU, Dazai and Chuuya are bitter enemies. They have fought on opposite sides of the battlefield for years, each carrying personal grudges against the other.
Dazai is an Alpha with a tragic past that has led him to avoid relationships, preferring a life of isolation. Chuuya, a fiery Omega, has always been loyal to the Port Mafia, but he's been growing tired of the endless bloodshed. Their hatred for each other is intense, fueled by the expectations of their respective roles in the Mafia world, and their differing philosophies on life and loyalty.
But fate has a cruel sense of humor, and when an unexpected encounter leads them to share a deeply intimate and forbidden night together, things begin to change. As the story progresses, both men are forced to confront their own feelings, their insecurities, and the trauma that has shaped them.
