So maybe Jun not only killed Yeon Woo's parents but also the policemen (with Yeon's help)? I guess all those hands in the house belong to the people they killed? And now everyone that gets in their way or try to separate them end up really bad or dead? It's like they're a psycho couple meant for each other and go on in life on a killing spree ever since the incident in the house, which sealed their bond in blood and will continue the same way forever.
