[When Set released him, Byleth took half a step back for extra measure and turned away to pick up the heavy crate he had been manhandling before Set had snagged his interest. His skin felt feverishly hot where Set's fingers had been wrapped around his jaw.]

It's alright. I can go days before I need to eat.

[And the others were far frailer when it came to calorie intake, he had noticed. Better for Byleth to endure a few days of harmless hunger pangs than potentially lowering the combat effectiveness of his comrades via weakness brought on by hunger. He readjusted his grip on the crate, and gave Set a... not a smile, because they weren't that close yet, but his blank expression was far softer around the edges than they usually were.]

Thank you for your kind consideration, however. It's nice, how you look out for your comrades.

[Set truly is tsundere... outwardly prickly and quick to call you annoying, but also reminding you to eat and telling you how you're not a walking abomination... what a nice person....]
