Glancing at herself in the reflection of the polished until it gleamed storefront window, Jiro was grateful for the bitter cold. Made excusing away her brightly flushed face all the easier. She scrunched down into the large scarf wrapped around her neck. Courteous of Mina, who was largely the one responsible for putting together her outfit. While Jiro liked her sense of style and was rather proud of it, today…well, today was special. A fresh splash of heat rose in her cheeks. A sense of giddiness bloomed in the center of her chest, prompting her heart to start racing. She gave her head a slight shake. Nope, nope, nope, she wasn’t going to jump the gun here. Right now was not the time to get excited. If she did, she was going to psych herself out and turn tail and run when time called for action. 

She stepped off to the side, came to a stop and took a deep breath. Her hands curled into loose fists in the pockets of her coat. Today…today was the day. She was going to do it…she was going to kiss her boyfriend. Just the thought alone brought on a huge rush of heat. If she were in a cartoon, steam would come bursting out of her head at that moment. Groaning softly, Jiro’s shoulders slumped. The thing was…she knew Kirishima loved her. He wasn’t exactly shy about declaring his love for her at every opportunity, leading to a lot of embarrassment on her part…not that she disliked that sort of thing. While he was affectionate, kissing wasn’t something they’d ever done. They’d been together for three months now and were still at the handholding phase. She had, originally, thought that Kirishima might just be shy about that sort of the thing but Uraraka-san had pointed out it might not be that. Rather, it might be that Kirishima was waiting to get some kind of sign from her that kissing was okay. 

Once Uraraka-san had said that, Jiro knew that it had to be true. Kirishima had reduced a lot of the distance between them but stopping just short, letting her close that last inch. It was exactly like him. She was honestly a little irritated that she needed someone to point it out to her. So, that was the reason behind their date today…well, that and she just liked being with him. Today, she was going to close that last remaining distance. Today, she was going to kiss her boyfriend for the first time. Another intense rush of heat. Jiro pressed her hands to her burning face. 

That is, if she could actually dredge up the courage to do so. This was way outside her comfort zone! Still…she wanted to. She really wanted to kiss Kirishima. She just didn’t know if she could be the one who initiated it…but if she didn’t, Kirishima would keep waiting and waiting. She didn’t want to make him think that she didn’t want to kiss him! Jiro crossed her arms over her chest, staring down at the sidewalk. That was the last kind of signal she wanted to be sending. She…she just needed to be brave. She was a UA student! On her way to becoming a Hero! If she couldn’t find the courage to kiss her boyfriend, then how was she ever going to make it in the world of Pros and Villains? That’s right, she just had to straighten her spine, look Kirishima in the eye and k…ki…kiss him…That annoying heat came souring in again. Jiro slumped, her head falling forward. 

This was going to be harder than she thought. 

“Oi, Jiro!” A familiar voice called out exuberantly from behind her, making her jump with a squeak. 

Whirling around, her heart leapt up into her throat. Kirishima was standing directly behind her, the tip of his nose and ears tinged pink from the cold. A bright, wide smile stretched across his face. Jiro’s heart thudded wildly inside her chest. Kirishima began to talk but she couldn’t hear him over the roar of blood in her ears. This was it…this was it! She could do it! Just…later, she would do it later, after she had scrounged up enough courage. Jiro’s hands clenched. No…no, no, that wasn’t going to work! She…she had to do it now! If she waited, she was going to talk herself out of it! No, while she was burning with Plus Ultra energy, she…she was going to do it! 

It wasn’t exactly…graceful. Stepping forward, she clapped her cold hands onto Kirishima’s cheeks and yanked his head down at the same time she was pushing up onto the balls of her feet. Thankfully, by the grace of some divine being, she managed to slow down just as their faces were coming together. She squeezed her eyes tightly closed, pressed her lips to Kirishima’s and lingered there just long enough to marvel at how smooth Kirishima’s lips were before pulling away with a gasp. Kirishima’s mouth hung open slightly. His eyes were stretched wide. Scalding heat rose up into her face at the same rate that Kirishima’s face went redder than his hair. They stared silently at each other for long enough that Jiro started to worry she had read the situation wrong, that Kirishima actually really was shy about this and that she had just crossed a major boundary. Frantic thoughts whizzed through her head. She was about to pull away and apologize when Kirishima’s expression softened. 

Exhaling slowly, he reached up to cover the back of her hands with his bigger ones. Warmth flooded into his eyes. The corners of his lips curled up into a pleased, delighted smile. Leaning in close, chuckling when she jumped a little, the heat in her face deepening even further, Kirishima murmured, “Can I?”

Swallowing hard, feeling as though her heart might give out from going so fast, Jiro shakily nodded. They were out in public but…no one was paying attention to them. Even if they were, she…she really wanted to kiss him again. Smiling sweetly, Kirishima’s moved in, pressing his lips to hers in a firmer, more confident kiss. Jiro’s eyes fluttered closed. She inhaled deeply through her nose, pulling in a lungful of Kirishima’s scent. This…this was worth every bit of embarrassment. She should’ve done this weeks ago but at least, she had done it. Now, well, now, she wasn’t going to be able to go a single day without getting one of these. Thankfully, she got the feeling that Kirishima was going to be the same.
