After Breaking Up with My Boyfriend, I Died a Horrible Death in a Basement

Has Anyone Read This Book?

Looking for a book: the female lead had amnesia and was rescued by a family. Later, she was in a car accident and regained her memories. The female lead she remembered herself as was a mafia boss. She later rescued a mayor's son, who may have been named Ruofei. The family who saved her was surnamed Lan. If anyone knows it, please tell me. Thank you.
