When Satoru first hears the expletive tumble from his kid's mouth, he stops what he's doing and stares. He blinks once, twice, and soon pats his kid's head. A wide grin grows on his lips, and he looks almost... proud? It kinda reminds him of himself when he was younger.

His child has a confused look while staring at him. "Why not, papa?"
