Am i the only one confused about the timeline?

She went back to a year before she was dumped, at the beginning of her fiance’s affair. After that, she can’t jump back more than a few minutes at a time bc she depleted her magic in the first jump

Yeah the note about those two getting engaged is a mistake, thats when they started their affair. She is either already or assumed as princes fiancé, but the official betrothal ball, which she got disowned at last time, hasn’t happened yet. Probably a wait until both have come of age thing if I had to guess.
