Even tho all clues were pointing at him, I really didn't want to believe it. But his father is indeed the serial…
Young Yeon woo didn't know that haejoon was his son....so I guess when he discovered about the secret roon in hae joon's house he used the time machine to kill Hae Joon in future
why? hes a good talented actor especially for violence character. no doubt that.
No hate for him but I really don't like him as an actor....he lacks in acting,......and you're right that he's good in violent roles and he's getting type casted for this reason......either he's choosen for a sweet lover boy character or a psycho type character....
And I'm not a terrorist
