It was strange to see another person more faithful in his relationship to Ryuutaro than he himself had. It was almost sad how much he had lost believe that things with his son would ever turn back right... if they had been right to begin with. He didn't want to see his mistakes, but he could see the way Ryuutaro looked at him just too clearly to ignore it.

"That's beside the point!", he roughly got Gokudera's self-blaming off. "Musing about what could have done differently doesn't make any difference right here and now, so you should end that right now."
Nobuhiro let out a sigh, almost seeming exhausted.
"... Ryuutaro's strong, huh? I'm not surprised. But he's still a child and he has not grown up like you. I ensured he would never witness anything this cruel, so that he wouldn't get used to it. It's not about what you have done or not done, that's past. I want to know what you can do from now on to ensure his well-being."
