you, katsuki, and kirishima have been friends for a while, especially because you guys met while at one of you guys mutual friends band performance (mina is one of those street preformers). Of course you and eijiro got along amazing, while Katsuki third wheeled alot of hang outs. Of course he liked you, but he was a stubborn asshole.
On this specific day it was super nice out as always and of course you guys went to the beach. Well Katsuki was paddle boarding kirishima was yapping away about food and some of the things you guys mutual friends did when You guys where kids.
"And when he landed it tore through the damn thing!" He was smiling having the time of his life with the two of you, you where eventually floating on the water if the surface and Katsuki was standing on his board while kirishima counties to yap away.
You where busy underwater looking at fish, kirishima was sat on his board. Katsuki was hardcore judging him for being so loud, even though he was as loud as a bomb half the time.
katsuki was making sure your board didn't float away having the velcro strap attached to his wrist as he watched you, admiring you but also waiting for some snarky comeback after kirishima said something.
