prompt: cheek kiss
He knows that it shouldn't mean as much to him as it does—Hiyori clearly meant what she did in a purely platonic way and nothing more.
(She knows it shouldn't mean anything more to her than it should. He clearly isn't interested in her like that.)
It was just a simple kiss on the cheek; it wasn't like he had never received one before, Kofuku had kissed his cheek plenty of times and he was fine. Sure, he'd occasionally blush but with Hiyori—he didn't even want to think about how he had reacted because he'd probably be the very definition of embarrassed—so he tried not to think about it. Yato tried his best not think about it but he couldn't help it. Every time his mind had a minute to think about anything apart from what he was doing—he was thinking about Hiyori. (And maybe about how he could gladly get used to her kissing his cheek.)
(She decided that it was just a simple kiss on the cheek—she kissed her mother and father on the cheek on a daily basis, she'd kissed a few other people on the cheek too and so she didn't expect it to be this big of a deal when she kissed him on the cheek. He was just Yato, annoying, annoying Yato—not someone she should be blushing over. But it just didn't seem to work like that as she noticed herself blushing over him more often than not—which annoyed her to no end.)
Hiyori was pretty, Yato knew that and anyone would be a fool not to think so but he had never dwelled on the thought of someone just because he found them attractive. Yato had found loads of people attractive in his life, it wasn't a irregular occurrence—but Hiyori was someone that he just couldn't stop thinking about. It wasn't even just the way she looked, it was everything about her that caught his attention nowadays.
(She hated herself for liking Yato—Yato was something completely different to what she was used to. Yato was unruly, loud and just plain strange—most of the time anyway. Yato had his moments where even Hiyori admitted to herself that it was okay to blush over him. Hiyori wasn't used to the feeling of blushing over someone. She'd blushed over people before but usually they were wrestlers that were quite a fair bit older than her. Hiyori didn't like blushing over Yato. It annoyed her, Yato was Yato and Yato was annoying.)
He doesn't want to admit he likes her and although Yukine is slowly catching on, always grinning at the two of them—stupid teenagers—he just doesn't want to admit that he likes Hiyori. He's not sure whether it's because of the fear of rejection or whether it's because he's Yato and she's Hiyori and they're two different people completely, he just can't bring himself to admit that he likes her.
(She's admitted she likes him to herself and that's about as far as she can go. Her friends still ask her if she likes anyone—she always says no because she can't tell them about the boy with the gleaming blue eyes and the soul that's painted with mischief.)
He decides that maybe one day he'll tell her how he feels. He wants her to kiss him more often.
(She decides that she's going to tell him how she feels soon. Kissing him on the cheek just isn't enough.)
