The internal sigh of relief is probably obvious enough but it could pass off as Nao just being happy that he likes the food, yeah? Let's leave it at that. But maybe Hawk's aware enough that he can point out the irony in his name. It earns a laugh from him. It's nice to meet someone with a good sense of humor!

"Heheh! Thanks~! Hisami Naoto~ But just Nao or Naoto is fine. Maybe whenever I score some ingredients I can make...dude, are you okay?" He leans in a bit with his form still in his mouth, making sure that he's not just imagining things. "You look kind of sweaty. Did you eat something spicy?"

It certainly wasn't from his potatoes.
