The first thing Kang-Joon noticed was that Do-Hyun stopped oversleeping.
He used to be the last one out of bed. Not excessively so; just enough that someone would knock on his door once, sometimes twice. He'd answer groggily, hair sticking up, voice thick with sleep.
Now he was already dressed when Kang-Joon woke up.
The dorm was quiet. Too quiet. Kang-Joon checked the time and frowned. It was earlier than their call time by almost an hour.
Do-Hyun sat at the small kitchen table with a notebook open in front of him.
He wasn't writing.
His eyes moved across the page slowly, as if rereading the same line again and again.
"You're up early," Kang-Joon said.
Do-Hyun looked up at once. "Good morning, hyung."
His voice was clear. Awake. Alert.
Kang-Joon glanced at the notebook. It was filled with practice notes—formations, counts, reminders written in neat handwriting.
"You didn't sleep?" Kang-Joon asked.
"I slept," Do-Hyun answered. "Enough."
"How much is enough?"
