Female lead was sick and died which lead to her transmigrated into a novel she read.She takes the place of the original cannon fodder that was meant to die by her fake parents.The cannon fodder though was actually the daughter of a noble family but the nanny replaced her with her daughter which is the novel's original female protagonist.Our FL was able to escape and hitched a carriage ride with our future ML. He of course is of high status but was hiding his identity like always. The FL ends up saving a prince that was suppose to die in the novel at the age of 9?He was drowning but it turns out that someone was trying to kill him while making it look like an accident.She ends up meeting the emperor and the empress. Turns out the empress was an old friend of the FL's mother.So she instantly recognized her appearance and her birth mark. The empress finds out the truth behind the FL's situation and what she went through and was furious.She was going to send back the FL to her original family but noticed that they were being bias with the fake aka original female protagonist(white lotus). Since she kept acting like a victim the grandma didn't kick her out.The brothers found out and saw through the original female protagonist act and showed their disgust of her. The empress took pity on our FL and gave her a house to live on her own. That's where I stopped and don't remember much.I probably put in some info wrong too. First time doing this so idk if I did it right
Omg it deleted everything so I had to retype it again only cuz I want to know what novel this is that I put this much effort.
