Most people don't necessarily change but it doesn't mean that they can't be better or worse than the current. In my eye, the prince's obsession towards Aristia stayed true, in the past it took the worst turn into loathing and the second time it became longing. It's a simple way for Ji-Eun to stir Tia all in all. Simple and cheap.
Idk I agreed with tia when she made the point of changing as a person and not living her life for revenge but when jiuen brought up the point that tia is making up excuses for her to continue her love for ruve which she held so long and desperately in the 1st timeline, well I had her give that. To this day I don't really understand tia's infatuation with ruve? For example why? And when ?
As much as I don't like jiuen she makes some valid points ngl
