Oof :< She prevented the death she knew only to have another one in waiting.
This does seem like someone out there has been trying to kill the two though, so maybe we're due another time rewind again after Hari figure something out.
So were they murdered the first and second time. Why just the parents though, in her past life their house was being run by the brother and they seemed ok financially so no one is trying to ruin their house or they'd kill everyone over the years.
