It was a theory from a while ago that the man chasing Aaron with a gun when he was a child, is Yujin’s father. He mentioned that the man looked eerily close to Yujin, and since the wife was obsessed with Aaron. He probably felt bitter about him, even tho it makes no sense to target children just because he was an incompetent father/ husband

Is the father targeting Aaron? If he is the his reasoning is stupid. He was a child, both of them were children back then, it was not their fault that his wide died. He just wanted someone to blame for his incompetence
