@Ning0my She did not. Regression means the character return back to a specific point in time with almost all or most of their memories, more like a time travel. In her case, she mentioned in Chapter 1 that she remembered being an orphan who froze to death likely in the modern era before, then reincarnated as Sasha and futher explained some details from the novel that occurred after their confinement where "Sasha" and the brothers have already become villains. So, she basically did not have the whole grasp of their current situation.
