Inigo's cheeks are still a little pink. Perhaps still out of embarrassment for how stupid that must have looked, or maybe since he can realise that Taiki is amused by it.. But he's just doing the right thing here! Gyousou isn't just a king in title, his whole personality seems to scream king. It very naturally makes Inigo want to act at least a bit more respectful than he usually would.

Once Gyousou seems to have grabbed the food he wants though, Inigo no longer hesitates. He grabs one of the pieces of fruit and just shoves it right into his mouth, taking a way too big chunk out of it as his first bite. His cheeks are sticking out like a hamster's. Apparently someone here was more hungry than he was letting on to.

"Bwoh, it's bwo gwood!"

(Well, I did say 'act respectful', not 'display actual manners'..)
