She did that in an attempt the made Jade angry. You know, so he'd grow up to be a tyrant so that the original flow of the story could be resumed and she can go back to her original world.
Not quite. She gave up on her mission. Now she just wants to live her life but at the same time push Jade to the path of a tyrant. The story is already way different from the novel and Viche is aware that fulfilling her mission is impossible, the story changed completely. She even mentioned this. Her goal is to lead her life happily and push Jade to his fate of being a tyrant. At the beggining she said she gave up the original plot, perhaps she still hopes to return to her original world but it's not so important anymore.
She wants to make Jade a tyrant by her action so she don't have to do it by dying.
idc if she's being stupid in her 2nd life cuz she have to adapted in that world...but why is she being more and more stupid in her 3rd life?? she's also dense and why did she always break the things in her house lmao...she's throwing fit like a real 10yo even tho i don't do that when i was 5yo...i mean she already live for the 3rd life but her thinking is like a kid that don't know anything...can someone explain this for me..is her brain also reset to 10 yo when she travel back to the past?(￣∇￣")
