Well, he is really is her little brother. She is not just a stranger reincarnated from modern world.
And in her life in modern world, she is actually kinda a villainess on her own. She used many method to raise in rank, and some of her scheme actually ruins couple of people.......
Her modern life was her 2nd life, while her 1st life was that one when her little brother caused her demise. Though the brother was not the one killed her directly.... it was her husband (the stalker) that tortured and killed her in 1st life.
But yeah, 1st life little brother is the one who forced her to marry the stalker....
I love the fl but I lowkey feel like she’s too nice jus saying n maybe I might be wrong cuz I’m only on chapter 10 but I wouldn’t be nice to a person who attempted to kill me like 2 times I love the art style of ts manhua tho
