If anything, Yoshida's trying to act like her dad, as young as he is for the role. Typically an older brother wouldn't be doing what he's doing, but of course under more special circumstances one would.
lol hope she doesn't end up writing garbo pseudo-literature... who am I kidding? she'd end up writing some gritty teen drama(s) or doing some adventure type shit. She'd fit right into it all things considered.
