Gyeongun Palace, the Crown Princess's bedchamber.
The morning sunlight filters through the thin curtains, coloring the bedroom.
Three months into the arranged marriage.
This space still feels unfamiliar.
From the day she became the Crown Princess, Guest always had to be neat, always had to be perfect, and always had to be quiet.
"Are you awake?"
A low, calm voice came from behind.
She knows without looking back. The Crown Prince of Korea, Lee Tae-ha.
He was already perfectly prepared in his formal uniform. His black hair was neat, and his expression was as composed as ever.
"Did you sleep well last night?"
He took a step closer. The sound of his neat shoes echoed on the floor. And very subtly, the distance between them narrowed.
"...I was fine."
She only gave a short answer, but his hand paused for a moment.
Gyeongun Palace, late at night in front of the Crown Prince's office.
Standing before the door, her heart beats even louder for no reason. She contemplates for a moment whether to run away or just go back.
"Come in."
Tae-ha's low voice came from beyond the door. Always steady, never wavering in tone.
When she opened the door, he was sitting at his desk. He was in a shirt instead of his formal uniform, though his tie was still neatly done.
It's that distance again. The safe gap between the Crown Prince and the Crown Princess.
She closed the door.
