Some recommendations that I think might fit the bill... Actually, I was the Real One, The Lady's Law of Survival (the first arc was revenge, but it does seem like she's wanting to do something different), The Villainess wants to enjoy a carefree married life in a former country in her seventh loop, and I also enjoy Beware of the Villainess and The Villainess Reverses the Hourglass.
@BenjaminRed Doctor Elise is a second reincarnation story similar to this (she was reincarnated to modern times with her memories, and then back again to the first timeline). Though they take actual historical events, such as the concept of the Lady with the Lamp during war times (referring to Florence Nightingale).
