One connection I dint understand. Jin jae gyu when he was 7 or 8 years old his mother will be killed and after that he was sent to some mental hospital and over there he meets some one (From a brick a person catches his hand) and after that he escapes and tries to live normal life, then he gets married and as doctor says he may die soon, so he plans to give his money to his wife after his death (If he dies) and she has a daughter, and she plans to kill him by poisoning his food but he will finds out it is poisoned and then he even finds out for his money she is planning to kill him and also her daughter, so for saving the little girl he kills his wife and her boyfriend. And then the little girl thinks her father killed her so she runs away from home. Then later jin jae gyu feels someone is watching him and erasing his memories and following him, even though he installs camera he won't findout anything, Jin jae gyu runs away from the country and he return after 20 years maybe and again he feels Eraser is following him, which is present. NOW I DONT GET THIS POINT. ERASER IS DONG BAEK SISTER, WE WILL KNOW THIS IN THE LAST EPISODE. BUT ERASER STORY STARTS FROM 2000 (20 YEARS BACK FROM PRESENT) BUT JIN JAE GYU KNOWS ERASER MORE THEN 20 YEARS ... HOW IS THIS POSSIBLE???? Did I miss any thing KEY point???? Linking between ERASER AND JIN JAE GYU????? Can anyone tell me....
