"ARE YOU sure, Wookie?" Yujin asked the doppelganger while making pan-seared steak in butter sauce. "Shin Aera is going to die?"
Wook, who was munching on some raw asparagus, said. "The ghost that possessed Shin Aera is the vengeful type. It's the type that likes feeding off of negative energy from a human who has a lot of anger in their heart."
[Shin Aera certainly fits the bill since she's a bully who has anger management issues.]
"If Shin Aera is going to die in three days, then is it safe to assume that the ghost has been feeding off of her negative energy for quite some time now?" she asked curiously. "Is that why she's so mean to me?"
"You can say that," the doppelganger said while nodding. "Ghosts that possess humans are like parasites. They can negatively influence how the humans they possess act."
