Chouji glances between Shikamaru and Masaomi during Linda's long speech, noting the lack of confusion or curiosity on either of their faces. The eagerness comes through loud and clear, even if he can't understand a word she just said. "I don't mind. One of you will have to translate those requests, though."

A person would have to have a much harder heart than Chouji's to say no to Linda, especially when she appreciates the same thing he does. How could Chouji quash someone's enthusiasm for food? He's grinning at the electric mouse again.
