The handkerchief from that day became destiny.

The library of the Bellart Empire was always quiet, despite being in the middle of the city. The interior, packed with bookshelves, was a place where the sound of turning pages reached you before human footsteps—a place where one could briefly escape the Imperial Palace.
That was why I chose it. There was no better place to disappear for a while.
That day was no different. I sneaked into the library to avoid the scheduled reporting times and prying eyes, but I ended up leaving without even opening a single book.
The moment I stepped out of the library, the rain poured down.
Reflexively, I took shelter behind the building. It was under an arched shade near the garden connected to the library.
Someone was already there.
It was a girl wearing a light-colored cloak. Her face was unfamiliar, but my gaze was drawn to her first.
It was just a brief meeting of eyes, but strangely, I couldn't be the first to look away. When raindrops began to wet my sleeve, she quietly approached and held out a handkerchief.
"Here."

I took it from her without a word. Even after her hand pulled away, the warmth of the handkerchief seemed to linger a bit longer.
"Will you be coming to the library tomorrow?"
It sounded like a question, but her tone was somehow composed.
"Please return it then."
After saying that, she stepped back into the rain. I stood there for a long time. Holding the handkerchief, I looked back at the library again. From the place I had entered to escape for a moment, I had gained a reason to return.

The aide who catches the runaway Crown Prince
The next day arrived. Morning in the Imperial Palace always flowed in a set order. Reports, schedules, people. Nothing was different from yesterday.
Except for one thing: the place he intended to go.
As he passed through the hallway to head to the library, a familiar presence followed from behind.
I'll be late.
He spoke without stopping his pace. He gave an answer, but he had no intention of explaining. Luen didn't say anything more. Instead, he naturally followed while maintaining a set distance from Kaisan.
Just as he always had. Kaisan turned another corner in the hallway. Then another. It was a path he wouldn't have normally chosen. There were a few such passages in the palace. Paths known to those who knew them, where one could briefly avoid prying eyes.
After a moment, the following footsteps grew distant. Only then did he slow his pace.
It wasn't so much to deceive anyone, but rather because he wanted to be alone today.
The library was no different from yesterday. It was quiet, and the sunlight filtered low through the windows. He took a few more steps inside and suddenly stopped.
At one of the seats by the window, someone was already sitting. A light-colored cloak, the figure reading a book with her head bowed. It wasn't the look of someone seeking shelter from the rain, but the look of someone who had come to keep a promise.
The fact that she had arrived before him strangely put his mind at ease. He didn't speak to her yet.
Kaisan didn't even take out the handkerchief. However, one thing was certain. His choice to come here was not wrong.
