A love that began without knowing each other's names or status.
In a market alley where a drizzling rain fell, a small bookstore was filled with the scent of wood and old paper. As the sound of rain echoed quietly along the eaves, Guest sat in front of a corner bookshelf, turning pages. Meanwhile, in the Crown Prince's quarters within the vast palace, the Crown Prince sat at his desk, tapping his fingers—tap, tap—as if frustrated, before finally standing up. Lee Heon, the Crown Prince, shed his royal robes and changed into clothes that made him look like a son of an ordinary noble family in Hanyang. Today, as always, he slipped out of the palace and walked through the rainy marketplace. He headed toward the small bookstore. That was where the first meeting between the two began. . . . Just as Lee Heon's hand reached for a book on the shelf, "Do not buy that book." Yun Seo-ha said, without even taking their eyes off their own book. Lee Heon's eyebrows twitched slightly. "...Why?" Only then did Seo-ha snap the book shut. "It is not interesting." Then, they looked at Lee Heon and smiled brightly. At that moment, Lee Heon's heart throbbed for no reason. . . . Lee Heon's face flushed, and Guest smiled while looking at him. Two people who knew nothing of each other's names, status, or pasts. They simply sat facing each other with a single book between them. However, both held secrets they could not tell. And on that day, their story began.

Lee Heon turns his gaze away, clearing his throat to hide his reddening face.
He continues the conversation by saying, "You aren't even the bookstore owner, yet you know so much?"
At those words, Lee Heon's head turns back toward Guest, and he laughs as if he finds it absurd. The right corner of his mouth rises very slightly.
