That night, Ha-neul could not sleep.
She lay in her narrow bed, the photograph of her mother and Eun-ha clutched to her chest like a lifeline. The image was faded, creased, but the joy on Yuna's face was unmistakable. She looked young, barely older than Ha-neul herself with the same doe-like eyes, the same tentative smile. But there was something else in that smile. A secret. A knowing.
She knew what was coming, Ha-neul thought. And she still smiled.
The ceiling above her creaked. Her father was still awake, pacing in his room as he did most nights. He never slept well. Ha-neul had long stopped asking why.
She slipped out of bed and padded softly up the narrow staircase to the attic. The shop had been in their family for three generations, and the attic was a graveyard of forgotten things: broken violins, stacks of sheet music yellowed with age, boxes of old letters tied with ribbon, and a dusty gramophone that no longer worked.
But Ha-neul was not looking for any of that.
She remembered a conversation from years ago—her father, half-drunk on soju, muttering to himself as he sorted through boxes. "The key is not in the music. The key is in the silence between the notes." At the time, she thought it was nonsense. Now, she wondered.
She knelt beside a large wooden trunk, its hinges rusted and its lock broken. Inside, she found what she had always known was there but had been too afraid to open: her mother's things.
A silk scarf, still faintly smelling of jasmine. A pair of white gloves, delicate and lace-trimmed. A leather journal, its pages filled with elegant, looping handwriting. And beneath it all, a small wooden box, no bigger than her hand, inlaid with mother-of-pearl.
Ha-neul's fingers trembled as she lifted the box. It was not locked. She opened it.
Inside lay a single piano key, chipped, yellowed, broken at the edge. It was the middle C, the most important note on any keyboard. And carved into its surface, so faint she almost missed it, were three words:
Find the song.
Her heart pounded. She turned the key over in her hands, searching for more clues, but there was nothing else. Just that one key. That one message.
She closed her eyes and held it to her chest. For the first time, she did not feel fear. She felt—connected. As if her mother was reaching across the years, guiding her hand.
The next morning, Ha-neul arrived at the shop earlier than usual. Jae-won was already waiting outside, leaning against the doorframe with a cup of coffee in his hand. He looked tired, as if he hadn't slept either.
"Did you find anything?" he asked, straightening as she approached.
She pulled the key from her pocket and held it out. Jae-won took it carefully, turning it over in his long fingers. His eyes widened.
"This is from a Steinway," he said quietly. "One of the old ones. Handcrafted. My grandfather had one in the hall's private collection the same piano your mother played on the night she"
He stopped. He didn't need to finish.
"The same piano," Ha-neul whispered. "Where is it now?"
Jae-won's expression darkened. "Destroyed. After the fall, my grandfather ordered it smashed. He said it was cursed. He said it had killed her."
"Did you believe him?"
He looked at her—really looked—and for a moment, the cold mask he wore slipped entirely. "No," he said. "I believed someone else killed her. And they used that piano to do it."
The wind howled through the alley. Dead leaves swirled around their feet. Ha-neul felt the temperature drop, as if the city itself was listening.
"Then we need to find the truth," she said firmly. "Not the story they told. Not the legend. The truth."
Jae-won nodded slowly. "There's someone who might know. An old sound engineer who worked at the hall that night. He's still alive—barely. Lives in a nursing home outside the city."
"Let's go," Ha-neul said without hesitation.
Jae-won raised an eyebrow. "Just like that? You don't even know me. You don't know if you can trust me."
She looked at him—this tall, haunted stranger who had walked into her life with a photograph and a secret. She should have been afraid. She should have been cautious.
But her mother's key was warm in her pocket, and for the first time in twenty years, Ha-neul felt like she was finally waking up.
"I don't trust you," she said honestly. "But I trust her. And she led you to me."
Jae-won's lips curved into the faintest hint of a smile the first she had seen from him.
"Fair enough," he said. "Then let's go find the old man. And pray he remembers more than he's forgotten."
