Kirishima pov
Almost instantly after setting up a couple blankets on the beach for all of our class, Uchida came to approach the group. He walked nervously over, fidgeting and messing with his clothes. Since we were all sat down engrossed in conversation, we looked up when he greeted us; all still in our costumes. "Hey guys. Really awesome in the parade," He sheepishly smiled as Kat and I, I nodded casually. "But I was just wondering, if, well- Mina, could we have a chat?" I was wondering why he was so shaky. Turning to Mina, I could feel she felt the same as him.
"Umm, sure, yeah." She replied, pulling herself up and going over to him. He gestured with his head to go somewhere else, and we watched them walk away. Kat leaned into my ear.
"Not that I care, but what do you think that's about?" He whispered. I just sighed.
"With Uchida, you never know."

Before long, Kat was lying down, resting his head in my lap. I played with his hair, trying to do braids and other hairstyles that failed nearly every time. "Quick! Someone, a hairband!" I laughed, pinching tight the plait I had made. My other arm extended to the group, hoping for something.
"This is so dumb Red." Moaned Kat as I began tying his hair with the band Momo gave me. Head still on my lap, I finished the hairstyle by taking a cute selfie of the two of us. It looked ridiculous since we still were dressed as kings, but non the less I still saved it as my screensaver.
"So what's everyone planning on doing when we get back?" Midoriya asked, fiddling with his knight helmet. Uraraka laughed.
"I think we can all agree to get a proper night of rest?"
"Well I need to re-dye my hair, Kat can help with that." I added in, still running my fingers through his golden locks.
"I just want some alone time with you." He smirked at me, raising his eyebrows. I gave him the 'really, in front of everyone' eyes after blushing. Looking up, a saw a few others go red, Kat also noticed. "Oh come on you virgins, it's not that big a deal."
"Well as you said Kat, most of the class are- you know-" I was trying to make everyone feel less awkward, instead they all laughed sheepishly. Great. And of course, Katsuki didn't make it any better;
"Oh come on, we're at that age now, and let's be honest, half of our class wants to fuck with each other anyways-"
"Kat!" I could see the whole group going redder and redder. Instead of stopping, he sat up.
"Like Deku and Uraraka, that's almost definitely a thing. Or Deku and Half n' Half, I'm in no position to judge-"
"Kat-"
"Ojiro and Hagakure, well unless you're into guys Ojiro-"
"Kat-"
"I'm just trying to be nice and inclusive. Like just look at Jiro and Yaoyorozu, a match made in Heave-"
"Katsuki Bakugou!" The yelling finally got to him as he stopped briefly before laughing. Just as I was about to push him into the sand, Mina walked over, looking content yet sad.
"Kiri, Bakugou, maybe we should speak."

We sat on a sand dune, with Kat's hand in mine. Mina messily played with the sand as she began speaking. "So obviously I just talked to Uchida, and it was basically all about us four."
"How come?" I asked, feeling Kat's grip tighten. She sighed with embarrassment.
"So, I should probably start this off by saying Uchida is bisexual- well that's what he thinks at the moment." I nodded, already assuming that was the case. "And, I didn't want to tell you this cause I thought you may be mad but- well this morning, you know when I went to speak to him?"
"Yes?" Kat said, hating how she was stalling. She winced.
"Well, I may have kissed him." I was shocked for a moment, but it also made perfect sense. "And I didn't want you to hate me again cause I kissed the guy you hate but- never mind." She threw a handful of sand in front of her.
"Well I'm not mad, just surprised. Anyways, what does this have to do with what you were talking about?" She nodded slowly, almost as if she was trying to find the words.
"He basically told me that- that he's really confused. He thinks he likes you," I could almost feel the anger radiating off Kat. "but then he also said he likes me and- and he's just really confused at everything. He said that he just needs to sort things out, learn who he is before he really acts on anything-"
"Oh he has another thing coming if he thinks he can try one on Red again-" Kat began to raise his voice, but I quickly hushed him.
"He said he'd ask the school for a therapist, since he can't go to his parents." She explained sadly. I had to admit, I did feel for him. Suddenly the brash voice of Katsuki interrupted the two of us.
"Okay, good luck to the kid and all, but like- can we just join the others again. This conversation is just so tiring and I'm sick of even thinking about this situation anymore, can we just enjoy our last night?"

We took Kat's advice. We spent the rest of the night laughing and talking and watching the sunset together. It was a magical evening that was quickly dispersed by our teacher, Aizawa, making his way onto the beach. "Well class, this was it, your last night. Now let's go back, get our bags, and head home."
