Nobuhiro had placed a hand on Ryuutaro's shoulder to keep him from walking back inside the room (his son did look like he was about to explode after all), but Ryuutaro angrily pushed it away, clenching his fists tightly.

As Bianchi arrived Nobuhiro was fast to respond. "No, these seem to be private matters and we're fine just waiti-"

At which a fan was very violently pointed as Nobuhiro's face, almost more of a hit than a shush. He smiled at Bianchi... and it didn't look very friendly or real either.

"'Fine' might not be the correct word for it, but I agree with him. You can't help him with anything, I'm afraid. And you could only help me if you made this" - he pointed the fan to the door - "stop, but I don't suppose you can."
It was five times more blunt than he usually would be, but he wasn't in the mood for anything else right now.
