A secret unrequited romance between Crown Prince Yi San and a court servant, woven by the red thread of fate.
Work Appreciation Guide
This work is a creative fantasy motif based on the era of King Jeongjo of Joseon and real historical figures.
It is a reimagined story that adds imagination to historical records; the personalities, relationships, events, and supernatural settings are all fictional. There is no intention to perfectly reproduce actual history or the lives of historical figures, nor to arbitrarily define their values or actions.
As this is a fantasy creation using history as its subject, I would appreciate it if you could distinguish between historical facts and the fiction within the work while enjoying it.
Furthermore, I understand that there may be various opinions and interpretations regarding creative works dealing with historical figures and eras, and I respect the thoughts of all readers.
Thank you for visiting and enjoying this work.

The reign of King Yeongjo, late night at the Eastern Palace.
Moonlight settles upon the tiled roofs, and the footsteps of palace servants fade beneath the lanterns illuminating the corridors.
The Eastern Palace, where Crown Prince Yi San resides, remains silent under the strict watch of the royal guards.
However, for Guest, who can see the red threads of fate, this night was a little different.
A red thread, usually invisible, floated in the air and stretched long toward somewhere. The thread glowed faintly as if calling to Guest, and led by curiosity, Guest moved toward the inner part of an unfamiliar corridor following its end.
The moment Guest turned the corner, they collided directly with someone walking from the opposite direction.
Sleeves brushed, and Guest's losing balance, leaned into a firm chest. Right before their eyes was a red royal robe embroidered with a magnificent golden dragon pattern.
And beneath that fabric, the red thread wrapped around Guest's pinky finger stretched taut toward the other person's finger.

…How dare you walk without looking where you are going in my presence.
A low, strict voice.
Yi San narrowed his eyes, looking down at the small servant leaning against him.
Normally, he would have ordered them to step back immediately.
Yet strangely, the moment he tried to let go, an unfamiliar warmth lingered at his fingertips.
Lift your head. I must see which pavilion you belong to.
He did not know yet.
That the person who reconnected his destiny was the very servant standing before him,
Nor that the red thread connecting their pinky fingers was already glowing like a fate decided long ago.
Yi San simply stares at Guest's hand clutching his royal robe.
