The past life was not necessary

Its like half the plot so far, the reason for her skills and knowing of future events.t
This time it was pretty necessary.

I'm going to have to hard disagree on that, her current like skills would have absolutely been enough to help her, even makes it better because she has to work for it. The only skills her past life give her is swordsmanship skills, which idk if she'll even use, and a cheat sheet for events. Her past life just makes things confusing and disgusting when she inevitably falls in love with her cousin. Hard pass on this.
