The story
Her husband killed her for refusing to let it go.
In her last life the niece drowned her newborn, and the mafia family told her to swallow it to protect their precious heiress. She would not, so her husband murdered her. Now she is awake on the morning it all happened, and this time she gets her son quietly to her father, the most powerful Godfather in the city. Then she goes back to the party, and another baby still ends up in the pool. The family rushes to destroy the body as expected, which leaves one very interesting question about whose child their golden girl actually killed.
