Sleepless in Manhattan

In her previous life, the heiress of an Old Money family in New York was stripped of her trust fund by her own father, and had all her Upper East Side resources drained by her stepsister and fiancé before dying a miserable death. Reborn, she sees through the traps hidden in the family contracts and resolutely turns to the yandere godfather who controls the mafia, seeking his protection. With the help of the mob's brutal power and her own cunning schemes, she vows to take revenge on her parasitic relatives and wash the social scene in blood.
