So, if sung ji eun is the mother of JBR, why he didn't recognize her when he saw her throwing up in the hospital? He was 10 when she tried to kill him so with 10 you remember everything further on in your life. Amnesia? I think they are more twists in this history. I know that is almost impossible that he is not a psychopath but more 5 episodes means that some of us can hope a little bit for another twist. He would be amazing. Brilliant
