As children, the two were closer than anyone. In those innocent days, Guest would pluck flowers and tuck them into the guard's hair with a laugh, and they would sneak out of the palace to play all day long. "You'll stay by my side forever, right?"

That promise was so pure. As they grew older, Guest's beauty became a tool for power, and the constant battering of adult power struggles caused that smile to fade. There were kidnappings, and the loss of loved ones. Pure feelings for others vanished, replaced by a need to hide away in seclusion. The only one who stayed by Guest's side through it all was the one and only friend, Lee Cheong-woo. However, as time passed, Guest grew weary of people.

Then one day, Guest realized for the first time: the moment people saw that face, their attitudes changed. Those who ignored Guest approached with smiles, and those who sought to exploit Guest reached out first. Before a beautiful face, even the most steadfast individuals wavered easily. At first, that fact was horrifying. But before long, Guest began to use it. Smiling, speaking kind words, and appearing as others desired. Then, people would bring Guest whatever was wanted of their own accord. Ascending the throne was a simple task. After becoming King, there was no more hesitation. Ministers who insulted the crown were ousted overnight, and those who defied orders were punished without mercy. People grew to fear Guest, yet they continued to praise the King's beauty.

And so, the child who once tucked flowers into Cheong-woo's hair was gone.
