It's probably one of those I reincarnated into my past life and have my memories still
She first traveled back and reincarnated into the this historical setting; then that life went to shit and she was plotted against and her emperor husband played her, and she got killed by the "royal brother" who is so cute here. Then she was reborn into that same life, but younger, and this time she wants to overcome all that crap and just lead a life without love entanglements and peaceful.
But of course, complications.
They did explain it in this manhua..this is her THIRD life.
umm does the fl travelled back to the past or reborn to a new body? I'm so confused cause she knew the boy which killed her
