she has to die acc to how she will originally die in the novel, i.e. killing the og fl then getting punished for it. so an early attempt or other ppl killing her wouldn't work. On why she can't just wait for the plot I think it has to do w the possibility that after she dies she'll just get reincarnated in this same world. So she has to escape from the causality or whatever of that world

Soooo like even if the female lead does even more terrible things than described in the novel in order for people to hate her more so that they will try to kill her sooner, thier early attempt to kill her wouldn't work? And if she wants to die, can't she just wait for the time in the novel where she's supposed to? I don't get why she's being so careful if she eventually gonna die anyways and her goal is to die. Also, now she knows someone in the other world has to die in order to return, but there's no guarantee someones gonna die at the right time and it would be her original body anyways cause like alot of time has passed since her body died so wouldn't her original body be decomposing? Sorry I got so many questions I'm a little confused :/ Can someone be king enough to explain?
