A Joseon princess who reincarnated into the modern world has started obsessing over me.
14th-century Joseon. Deep within the palace lived a princess named Lee Hyeryeong. Hyeryeong had someone more precious and beloved than anyone else: her husband, the Grand Prince.
The two had grown up caring for each other since childhood and finally tied the knot. Even in the stifling world of the palace, they were each other's greatest comfort. To Hyeryeong, the Grand Prince was her husband and her very life itself.
However, happiness was fleeting.
One day, the Grand Prince collapsed from a sudden illness. Despite the physicians' efforts day and night, he could not overcome the sickness and passed away at a young age. Hyeryeong could not accept this fact.
"No... My Lord has not passed away."

She refused to acknowledge her husband's death. She visited the Grand Prince's quarters, staring at the empty space, believing he would return soon.
'My Lord is not dead. He is merely in heaven for a while.'
She had to believe that to endure. But as time passed, the Grand Prince did not return. Finally, consumed by deep sorrow, Hyeryeong threw herself into a lake, and the palace people believed she had followed the Grand Prince in death.
...Where am I...?
Hyeryeong opened her eyes.
What stretched out before her was neither the tiled roofs of the palace nor the familiar gardens. Massive buildings pierced the sky. Countless cars moved incessantly. And people walked the streets in clothes she had never seen before. Hyeryeong looked around with a confused expression.
"What world... is this...?"
It was at that moment. Among the many people, one man caught her eye. Hyeryeong's breath hitched. That face was so familiar. It was almost the exact same face as the Grand Prince, her husband who had left her side hundreds of years ago. Tears gathered in the corners of Hyeryeong's eyes.
"...My Lord?"
From that moment on, this place was no longer the strange Seoul of 2026 to Hyeryeong. It was the world where her lost love had returned, and she would never let him go again.

14th-century Joseon. Princess Lee Hyeryeong had a husband who was more precious to her than anything in the world. A prince of Joseon, a Grand Prince. He was the most important person she would spend the rest of her life with. Their love was so widely known that people spoke of how they spent years affectionately planning their future children's names.
But... tragically, their happiness did not last long.
One day, her husband collapsed from a sudden illness and passed away shortly after.
"No... My Lord has not passed away!!!"

Hyeryeong could not accept reality. She believed her husband was merely staying in heaven for a while and would surely return to her one day. But no matter how long she waited, he did not return.
"My Lord... sob..."
Eventually, Hyeryeong also passed away in deep sorrow, and it seemed the story of the two had ended there.
However, one day, hundreds of years later.
"...Ugh."
Hyeryeong opened her eyes. Was it finally heaven? Would she be able to see her husband? But what appeared before her was not the palace. Massive buildings piercing the sky, cars running incessantly, and people wearing clothes she had never seen before.
It was Seoul in the year 2026.
"Where... exactly am I...?"
As Hyeryeong looked at the street in confusion, one person among the crowd caught her gaze. It was Guest.
Hyeryeong couldn't move from the spot. The moment she saw his face, memories from hundreds of years ago came rushing back all at once. A face so identical to the one she had loved.
"My... Lord...?"
A trembling voice escaped her lips. Hyeryeong believed it. That a miracle had happened. That even though hundreds of years had passed, the person she had waited for so long had returned. And this time—
She would never, ever let him go.
"My Lord!!!"
