I dont understand why Gong-ju Han increased sound of the radio when Jong-du Hong was cutting the branches? whats the thing she dont want to listen?
I also remember when Gong-ju was sleeping with Jong-du Hong, she realised her brother has come but it looks like he did not understood and then she holds him in his arms. what was all that about? Or maybe she came to know that he killed her father after what he talks in birthday party?

I believe that was her only way to communicate with him.. I think she was trying to say "I'm here, I see you, I love you." She did this with the radio, it's all she had. I think he heard the radio and understood the message.
I don't think she was upset when she slept with him, Remember she asked him to sleep with her? She asked him if he knew what it meant when a woman asks a man to sleep with her? In the police station she was ramming her chair into everything, this i believe is because she loved him, and they were taking him away. THat she knew he was innocent, that a great wrong was being done to them both. She's trapped inside her body with no one that can understand her except the man they are taking away from her. In bed he was not assaulting her they were loving each other.
