In the wake of Yeongjo’s order to kill everyone in possession of the book that makes him complicit in his brother’s death, Sun finally confronts him with the truth: Did he sign the maengui? Is he Juk-pa and does that mean that everything written in this book is true? Yeongjo quakes with rage to be confronted with the truth so head-on by Sun, and cries defensively, “‘How afraid were you? How difficult and scary was it? Didn’t someone threaten to kill you? If you didn’t sign that document, were you scared they would kill you?’ If you are my child… IF YOU ARE MY SON—that is what you should ask!” Father and son’s eyes are brimming with tears, and Sun drops to his knees as his tears spill out. He immediately realizes that he never considered it from his father’s perspective and begs forgiveness, acknowledging that being born his son (and therefore the rightful heir) means he can’t ever fathom the struggles Yeongjo went through as the king’s brother.
