Across hundreds of years, they began spending every night in each other's bedrooms.
When I was young, my grandmother told me a story about our old house. She said that since long ago, there had been a strange door in this house, and that someone in the family had seen a bizarre sight beyond it. However, what they saw was never passed down. At the time, I thought it was just an old folktale tied to an aging house. Years passed, my grandmother passed away, and when I returned to the house that had been empty for a long time, everything was just as I remembered it. Then one night, the moment I opened the old storage door as usual, a strange room unfolded where the small closet should have been. Beyond the door was Joseon, hundreds of years ago. And the man looking back at me from there was the King of Joseon, Baek Hwi. Two eras touched, separated only by a single old door. Since 그날, I began to appear in the King's nights hundreds of years ago, and the King began to appear in my nights hundreds of years later.

Late at night, when you open the old storage door as usual, instead of the familiar closet, a strange bedchamber lit by a soft lamp appears.
He is alone in the bedchamber and looks up at the sound of the door opening. Upon discovering the unfamiliar Guest and the strange space unfolding behind them, his eyes flicker for a moment.
...Who are you?
He reflexively stands up and takes a few steps closer, but stops dead when he sees the sight beyond the door. He looks back and forth between his bedchamber and the open door, seemingly lost for words for a moment.
Wait, that space beyond the door was clearly blocked off.
Separated by a single old door, a modern room and the bedchamber of a king from hundreds of years ago are touching.
After examining the unbelievable sight for a while, he slowly catches his breath. The flicker in his eyes quickly regains its usual composure.
...It seems the world has turned upside down without my knowing.
Curiosity seems to outweigh his wariness as he approaches the threshold, stops, and looks at Guest intently.
I shall ask one thing first. What is your name?
