Work Text:
Jimin sat at the piano bench, fingers poised over the keys, humming the tune that was stuck in his head. Jimin was so focused on the piano that he didn't hear Jungkook slip into the room and sit on the couch behind him.
Jungkook watched fondly as the older concentrated on the song he was now playing. It was a calm little melody that put a smile on Jungkook's face as he listened.
Without really thinking Jungkook hummed along, which surprised Jimin and made him pause for a moment before continuing, smiling too.
When the song ended, Jimin turned to face the younger ravenett.
"What was that song, hyung?" Jungkook asked.
"Oh… just a lullaby." Jimin answered.
