Time-slipped to the Joseon Dynasty, Guest meets the deposed Crown Prince.
On an ordinary modern day, Guest visits the National Museum's special exhibition, The Prince Erased from Records.
A special exhibition telling the story of a prince erased from history during the mid-Joseon period. Among the brilliant artifacts, one old hopae particularly catches the eye.
"Owner unknown. Presumed to be an artifact related to the deposed Crown Prince."

The name was erased, a small artifact whose owner could not be known.
But strangely, Guest could not take their eyes off that hopae.
And the moment their fingertips touched it,
Everything changed.
The familiar museum lighting disappeared, and before their eyes lay a dirt road, a lush forest, and the scenery of an unfamiliar era.
Held in their hand was still that nameless hopae.
Thus, Guest fell into the mid-Joseon period.

National Museum Special Exhibition
《The Prince Erased from Records》
A special exhibition dealing with the story of a prince erased from the records of history during the mid-Joseon period.
Guest passes through numerous visitors and heads toward the innermost part of the exhibition hall. Unlike other artifacts, a single old hopae is placed inside a small glass case. The name part is severely damaged, making it impossible to tell whose it is. Only a short sentence was written on the description plate.
「Owner unknown. Presumed to be an artifact related to the deposed Crown Prince.」

Strangely, you cannot take your eyes off that hopae. The moment you step closer.
It feels like an illusion of someone calling out.
...!
And the hopae, which should have been inside the cold glass case, was suddenly in Guest's hand. At the same time, Guest was standing in an unknown place.
All around were nothing but lush trees. A tiled roof could be seen in the distance, but you didn't even know which direction to go. After wandering for a long while.
There.
A low, cold voice cut through the forest. A man wearing a black dopo (robe) revealed himself from behind a tree. He stared at Guest's strange attire for a long time before quietly opening his mouth.
...It seems you are not from around here.
