She gently squeezed Soo-bin's hand.
"์๋น ๊ฐ ๋ ์ฐพ์ผ๋ฌ ์ฌ ๊ฑฐ์ผ."
Your dad will come looking for you.
The child began crying again.
And then she whispered something unexpected.
"์๋ง ๋ ธ๋ ๋ฃ๊ณ ์ถ์ด์."
I want to hear Mom's song.
Nia looked toward her.
"What song?"
Soo-bin swallowed.
Then, almost inaudibly, said the title.
"Haru Haru."
Nia stared.
She knew the song.
Of course she knew it.
For a moment, the crowded station seemed to fall away.
Then she smiled gently.
"๊ทธ ๋ ธ๋ ์์."
I know that song.
Soo-bin looked up.
Nia drew a slow breath.
And began singing.
At first, Soo-bin simply stared.
The song was familiar, but the voice belonged to a stranger. It wasn't her mother's voice, the one she remembered hearing in the kitchen on Sunday mornings or through the car speakers while her parents drove toward the coast. It was deeper and softer, carrying a gentle warmth that seemed to make the underground station feel less frightening.
Nia sang quietly, keeping the volume low enough that she could still hear instructions from station staff. She didn't try to perform for anyone, and she didn't care whether the notes were perfect. She simply watched Soo-bin's face and continued whenever the little girl's expression suggested she wanted to hear more.
Gradually, the child's trembling lessened. She stopped looking toward the crowd every few seconds and began listening, her fingers still wrapped tightly around Nia's hand. By the time a responder approached to check on her, Soo-bin was calm enough to explain what had happened and answer questions about her breathing.
Nia stopped singing.
Soo-bin looked up immediately.
"๊ณ์ ๋ถ๋ฌ์ฃผ์๋ฉด ์ ๋ผ์?"
Could you keep singing?
Nia smiled.
"์กฐ๊ธ ์๋ค๊ฐ ๋ ๋ถ๋ฌ์ค๊ฒ."
I'll sing again in a little while.
The child nodded.
Then she leaned closer and whispered something Nia would remember for the rest of her life.
"์๋ง๊ฐ ๋ถ๋ฌ์ฃผ๋ ๋ ธ๋์์."
It's the song my mother used to sing for me.
Nia felt tears gathering.
She didn't ask where the child's mother was. The sadness in Soo-bin's voice suggested that the answer might be painful, and she didn't want to turn a frightened child's moment of comfort into another difficult conversation.
Instead, she gently held her hand.
"์ ๋ง ์ข์ ๋ ธ๋๋ค."
It's a beautiful song.
Soo-bin smiled faintly.
And in the middle of a frightening emergency, surrounded by strangers and the distant sounds of sirens, the little girl finally seemed to believe that she might be safe.
Soo-bin's aunt found them twenty minutes later.
