“Yeah, yeah, whatever, Dad.” Dazai-kun rolls his eyes, choppy brown bangs falling over his forehead messily, a product of his refusal to listen to Mori when the older man tells him to take care of his hair better instead of just not brushing it and leaving it a tangled mess.

At first, Mori thought he had misheard Dazai-kun. Surely, his Demon Prodigy had said something else?

But judging by the stunned, almost appalled expression on Chuuya-kun’s face, who stood right beside Dazai-kun, Mori’s belief was proved wrong.

Mori shifts in his chair and clasps his gloved hands together in front of him. Dazai-kun was still saying something, probably complaining about how Mori gives them so much work to do, but Mori wasn’t quite listening. Chuuya-kun was looking back and forth between Mori and Dazai-kun, as if picturing them fitting the usual ‘father-and-son bond’.

“Dazai-kun,” Mori says gently, interrupting the young, rambling teenager. Dazai-kun looks vaguely irritated at being interrupted, but huffs and looks at Mori in exasperation. He was such a dramatic, sassy child. Mori opens his mouth to speak, but he can’t quite find a way to word it.

“You called the Boss ‘Dad.’” Chuuya-kun helpfully says.
