I'm not sure where you got that part from, that he went back to a time he wasn't born yet? Because he was definetely born at that time haha
When gongja regresses his body regresses too aka he gets younger.. sooo, no, he did not regress until he wasn't born yet. Which also means it was him as an adult who had already left the orphanage, because we can see that he's still in the tower when he went to kill the fireking
If he want back in time then why does the director know the grown up him or did I understand the story wrong???
