Isekai

Fl woke up into a strangers body only to find out it’s the villainess from her sisters book and thinks that this is her sister giving her a chance to relive a better life. she knows what’s happened in the story and made plans to make herself just a side character......(super slow) even when she butchered the story she still doesn’t do anything even though she wants the ‘main female lead’ to achieve the same ending as in the story
Not very interesting
