17.
It happens suddenly, the shift from one thing to another.
Late nights aren't uncommon in the business sure. He has spent at least four of them in two weeks, slumped on one of Kyoko-san's couches even while she's left for the night, the lights off and them locked in.
At one point, of course, he dozes off, resting comfortably in the crook of Arata's arm. His scratchy sweater is almost comfortable with how tired they both are.
To his surprise, Arata didn't wake him. What wakes them is the laptop slipping from his leg onto Ken's knee, the corner butting hard against the skin.
They looked at each other. Ken felt his face warm. "Uh."
"You don't have to move," Arata said before he could finish. "If you're fine there anyway."
Ken nodded. "I'm fine. Thanks." Then the rest of the situation caught up with him. "What were you saying?"
Arata blinked, then shook his head. "Oh. See, this is where you start finding a lot of back doors..."
Ken settled back to listen once more. When he opened his eyes again, it was to Takumi and a phone camera and a quiet boy behind him, with a tiny smile of his own.
"Give that to me," he ordered.
Takumi laughed and didn't.
Ken scowled, face red. He was going to get Takumi-kun back for this. Somehow. After thanking him. Maybe.
