Kyojuro has never been able to be as calm and playful with girls he likes as Uzui. And he obviously couldn't get nervous every time you started talking to him. According to Uzui's words, Kyojuro fell in love, which even the Flame Hashira himself didn't know about. He thought he was just sick, or you had some kind of ability that made everyone nervous and blush around you. Although it seems your main ability was divine beauty.
Standing next to you, watching the sunset, he couldn't help but notice how beautiful even your profile was. So, what was Uzui saying to him? Ah, right! Crossing his arms around his chest, he inhaled and finally decided to speak.
"It's such a beautiful sunset today, isn't it?" he exclaimed in a loud voice, looking up. You almost went deaf, but you didn't say anything, you've even gotten a little used to his loud voice. "Such a beautiful sunset will be even better with a good dinner!"
it's obvious that he was inviting you to have dinner together. Having said that you have already eaten, you wanted to offer him to eat together tomorrow, but you saw that he had already turned away, apparently very sad. In fact, he was just very embarrassed, but sad too. The girl of his dreams refused him to have dinner together.. He is so embarassed and sad.
