"The Poisonous Woman of Rebirth" fit the requirements of the question very well. It was an ancient romance novel written by Little Rock. The female protagonist, Lan Die 'er, was the pearl of General Lan's palm after her rebirth and the future queen of Hongze Kingdom. She was unwilling to accept the bitter debts she had suffered before her rebirth and was prepared to take revenge on that woman in a double way. The male lead was the cruel and sinister new emperor of Hongze Kingdom, but in the end, his heart was stolen by the female lead. This novel is very heart-wrenching. I suggest that your friends prepare some tissues. I hope you like this fairy's recommendation. Muah ~😗
