For eight years, Ye Fei and Gu Ang, two alphas who raised their ranks in the military, were lovers and did everything together. But then, soon after their marriage, Gu Ang asked for divorce. Unsure of the reasons why, Ye Fei became heartbroken. Unknown to the two of them, they woke up soon after their divorce eight years in the past; back when they were freshman; back before they ever met; back before they loved one another. Although the two of them have different views on being reborn, the main question is whether or not this world they were reborn in was exactly the same as their old world or not. Had they created a butterfly effect? Could they save the ones they had lost in those eight years? Were they still going to end up together? Soon they would learn that not everything was the same…. Something was entirely different than their old world… And that was Gu Ang’s secondary gender. He was now, unknowingly, an omega.
