I am very confused, even after chapter 13 I still don't understand about this plan 😅

Sure, thing! What do you need explained? (=・ω・=)

I'm dumb so everything. Firstly why did they even need a fake if the real one was alive? Secondly, what are her plans for her parents? Thirdly, is she really saying she's gonna be a part of the 'rebels' and destroy the system?? Like that's a lot of work you know?? Also wouldn't that be counter productive since half the comments section says CrownP is male lead? Also how does that directly affect the duchy??
