Help me look for this Manhwa please

So I was reading a manhwa and exit the chrome accidentally and now it's gone. I'm using incognito.


As far as I remember, FL is reincarnated. She was a saint but on the book she read before she died on her previous life the true saint will appear and she'll die (classic villainess story). She was the granddaughter of the duke or something and their relationship is not good at first. FL works hard to be a good saint but grandfather did not acknowledge it properly so she became troublemaker.


Then the "true saint appear". I think it's also from their family. The true saint tame the wild animal in front of everyone and people assume that FL is the fake one.


So a greedy uncle insist the grandpa to adopt that "true saint" but grandpa does not want to coz FLs position will be compromised. But FL insists to adopt her

That's all I remember. Hoping someone can help me

Thanks much!
