She survived, so this isn't an isekai story.
she died in chapter 10 and another soul (Su Luo) entered her body
Okay, so who's Su Luo?
Su Luo is the name of the soul in the body of the late Gu Qingcheng who time travelled from the future
Alright, but is there any reference to her existence in that future anywhere in the manwha? Because I seem to have missed it completely. (And thank you for pointing it out.)
Did she reincarnate or is she the same person ehhhhhhh I'm confused but I like strong FL so I'm rooting for her to behead that son of bitch with her own hands
