DARE I SAY I'LL TAKE THE LEAD

Being born the youngest is a drag and that is especially horrible if you are born a royal  princess with the cursed birthmark that matches the doomed prophecies of their kingdom's legend. Princess Joie Michiele Selova is a villain born and died tragically of pity and pain of one of my favorite trilogy novel "LE CŒUR ÉPHÉMÈRE"  which I happen to finish reading and re-reading for the story was full of fun magic lore  and intense scenes.  However due to truck-kun being a son of a truck bitch, I died saving the neighbor's kid and to add to the shitty luck I have, I had transmigrated as the seven year old version of the Villainess who's known to be spoiled and rotten to the core and the source of the conflicts of the main characters on the first and second book. Well I can't mope here might as well be my own person and be the coolest me I can and escape that shitty fate by telling my fiancé who I am and what he should do to bring end to the doom in the next ten years because I may be a villainess in this world, but dare I say I'll take the lead and end that un just fate...but will this really help me escape my fate before the events of the third book starts?
