Ryuutaro absolutely hated to have to do this Have to talk to his father, have to leave Hayato. It was the most frightening thought.
But he saw that is was necessary and that only made it worse.

So he all but rushed out of the room, his steps like more gunfire on the floor of the hallway as he caught his father just to get the address out of him. Because as far as Ryuutaro was concerned his father had absolutely no say in whether or not Hayato got brought there. He didn't like the thought, but everything was better than here.

So soon after he returned and at least could tell Bianchi the where in short words. He hated how she had talked to him, but right now he had no time to be nitpicky.
