Confuse

"Sorry if I suddenly invited you to dinner like this," said Elisio. "Oh yeah, you must be curious about the reason why I invited you to dinner at a romantic place like this?"

"Y-yes, I'm curious," replied Kin with a bit of a stutter.

Hearing Kin who stuttered, Elisio also became stuttered and had difficulty speaking normally. And now they were both silent again without a word.

They almost finished the food they ate, but until then they didn't say anything and just focused on their food. In fact, they just looked down without looking at each other. Very focused on the food they are eating at the time.

Or you could say, food is only used as a tool to divert activities. So that it seems busy and doesn't have anything to talk about.

They didn't even have anything to talk about.

Basically, the two of them were very talkative people. In fact, one could say that they were people who couldn't keep their mouths shut for long.
