Comment by piepostuch on Sadistic Beauty - Chapter 74

@piepostuch no. Wookyung said she was a vicious girl as soon he saw her. She had got no friends. She isolated herself in the literature club where she was the only one to stand up to Minho. Her brother Duchi afraid by her. He has known her since their childhood. So she was already sadistic. But psychopath females plays the victim card, are good at pretending. In fact, Duna was only handsome and shy in front of Minho ! Minho only saw the false Duna in her false world. She played a role in front of him. When Minho was not in front of her... remember Duna when she yelled at the boy (the first time Wookyung saw her) or Duna with Wookyung (she was happy to speak about strangle Minho). 
Duna is a psychopath who does not accept her true nature and who fantasizes. Wookyung is a psychopath who helped Duka to find herself.

@Red ok i hate them both tho lol
