"Yea...school or... [b]damn it[/b] Kaori listen, I can't just accept this food without paying for it, it just doesn't sit right with me..."

Kaori jumped at his outburst. She wasn't sure what the words 'damn it' meant but she could tell it wasn't very nice and he was clearly upset. At that moment it was very apparent just how much taller he was compared to her. It was as if she had disturbed some ancient spirit and now it was towering over her in anger. Had she violated some American custom that she wasn't aware of? She really couldn't understand why it was such a big deal to him. She had decided to pay for the food herself because it wasn't an inconvenience. Kaori wouldn't have agreed to cook for him if she didn't think she could fulfill that promise. 

She could hear other people talking who had noticed his outburst. 
"Why is he angry at that girl?" 
"Let's just leave them alone..." 
"He's yelling at his girlfriend..."

This made her feel even smaller and she started to blush. She didn't like being out in the open like this for people to see. She looked down at the ground, unsure of what to say. Earlier, when he bolted after her to return her tripod, he had the same look about him. It was scary but there was something else about it, something she didn't quite recognize. It wasn't anger exactly, it was more like... something else. She stood there for a few moments, clearly he felt like he had been wronged but why was such a seemingly trivial thing being treated as a major offense? Kaori couldn't imagine why, all she could do was apologize. "I-I'm sorry... Senpai"
