Basically FL died and got reborn in her favorite web novel series as a little girl to an abusive father. When she was running away she almost died and was saved. After she was saved she was taken in by the white hair guys family as a maid.
Years later white haired guy is engaged to the books original FL who hates him, she is in love with the prince. Because Original FL, who is a Saintess with the church, loves the prince and her fiance is a threat to his power she sets out to poison her fiance.
Our FL knows all this and so keeps white hair from drinking the poison Saintess put in his drink. But white haor mistakes our FL for being the assassin. To ensure he doesn't drink any of the poison she drinks it instead and a wacky side effect happens and she becomes a little kid again.
To repay her, and also to benefit himself, he makes a deal with the villain family. Our FL will be adopted by Villian family for 3 years. In that time the Villian family is to reverse the side effect(aka make her an adult again) @ which time white hair gives them control of a mine he owns. After the 3 years are up he plans to be engaged to, if not marry, our FL. In this way he relays her with wealth for saving his life, and he avoids an arranged marriage with an ally of the prince. Win win.
So our little FL goes off to Villian family, goes through trials, and wraps the oldest brother and the father around her finger by being cute and brave.
In the future she will likely do that to the other brother we havent met yet too.
Also, proven by the test and her surviving the poison ment for white hair, she seems to have some immunity to poison. Idk why.
Hope this helps clear up the story for u
Where are we??? I force myself to read it, multiple times and i still don't get what's going on :( . And is it only me that cannot tell the difference between the long dark hair father and son? ╥﹏╥
