The Mob Queen Wants Straight A's — Episode 5

Jade Kane, the ruthless, unseen ruler of the powerful Black Viper Group, dominated both the underworld and legitimate business worlds. She died saving high schooler Nina Sterling, who was pushed from a rooftop—only to wake up reborn in Nina’s body. Nina was the Sterling family’s long-lost biological daughter. After returning home from the countryside, she endured years of coldness and bullying from her family, all manipulated by the favored adopted sister Sienna, who ultimately pushed her down the stairs. With Nina’s memories flooding in, Jade swore to avenge her and take back what was stolen. Tired of endless violence from her past life, she only wanted to fulfill her unmet dream: going to college. Unfortunately, Nina was a dead-last student with terrible grades. Meanwhile, her loyal old subordinates recognized her. Enemies closed in: her exiled sister Maya and power-hungry Ichiro took advantage of her “death” to seize control. Sienna also colluded with outside forces for wealth and power.
