There's no point keeping too much back here in terms of what I do and don't know about the Driver. Might as well brazen it out, because I could learn something. We all put the Drivers on and just rely on experimentation and the inbuilt knowledge that comes with it, but there's probably a lot more...

"I don't know how much," I say cheerfully enough. "Quite a few things, yes, Ryouma-san."

...that's interesting. Does he mean nii-san hasn't been focusing enough? Or that he's worried about distractions in the future?

Am I a distraction?

"You don't want him to worry about anything else in his life?" I ask softly.
