Help

Idk if it was a novel...or manhwa but the storyline goes something like this:
FL is transmigrated (or reincarnated? Idr) to a novel where she is evil step mom to the FL of the novel so, she decides to marry the father of ml in the novel. That is how two supposedly protagonists ends up being siblings instead.I don't remember whether that trashy father to the FL in the novel dies or transmigrated FL actually divorces him....
But yeah

I just suddenly wanted to read this
