"Meat," he repeats with a sharp nod of his head as though that settles everything. He's made a decision and he won't be allowing anyone to change his mind. Unless, of course, Su-jin really doesn't like his decision, then Aqua's mind can be changed very easily. He just wants to be accommodating. "Let's have meat and fish for our meal tomorrow. I've never really had meat before." A sea creature who only dines on smaller sea creatures or simply a young man who was brought up pescatarian? At least someone whose senses aren't quite as keen as Su-jin's would probably just think the second option.
