Hisao groaned. He had gotten used to the running every morning, but he'd never gotten used to waking up this early. A quick splash of water to his face, a drink to ensure hydration, and a change of clothes, and it was time to head down to the track. Halfway there, though, his tired eyes wandered up at the sight of something unusual, and he stopped in his tracks.
 
"Rin, what the heck are you doing up there?"
 
"Up where?"
 
"You're sitting on top of the light post! How did you even get there!"
 
"I wanted to watch the sunrise."
 
"That doesn't explain anything."
 
"It's a different angle from here. I can see more. I'll paint it later. Interesting colors."
 
"Will you please tell me how you got up there? How will you get down?"
 
"No."
 
"What? Do you not know?"
 
Rin grinned. "I know. It's just more fun not to tell."
