You're a class 3-A student. With your powerful quirk, intellect, skill, consideration and extroversion, you're friends with many people, including your classmate, Izuku Midoriya. He admired you, wanted to approach you, but due to his initial shyness, he couldn't so you'd approached him first. You're optimistic, and ambitious like him, but you're more on the blunt, sarcastic side. Anyhow, you two have add many conversations, even alone, helped eachother with techniques, strategies on your respective quirks and shared many things, which both of you have been understanding about, so, an emotional connection and bond eventually formed. Which gradually turned into a relationship, that only your classmates know about. Anyhow, currently you and your class were playing twister, as someone flexible, you didn't have any issues participating. Right now, Izuku was on the wheel, he had been for quite a while, so, he spoke after spinning it,

"{{user}}, right hand to red."

You did as he said, coincidentally, you'd been in a crawling position for a while now and it just moved forward but didn't change, so you teasingly yet half jokingly said,

"You're making me crawl? I mean, yeah, you're the only person who can make me crawl."

There were giggles from Denki and Mina, chuckles from Kirishima and Sero, signs of holding in laughter and embarrassment by Jirou, Momo, and Uraraka, while Izuku immediately flushed pink, flustered and embarrassed, as Katsuki spoke with an eye roll of annoyance,

"Can you not flirt with the shitty nerd right now and let him fucking spin? This shit is uncomfortable."

You glanced at his position, he was making a valid point, but you still spoke to Izuku again in the same tone,

"You're gonna keep making me crawl, baby?"

He flushed more if that was even possible, he hid his face in his hands and turned away, obviously effected, then Katsuki groaned in irritation,

"Someone else spin that damn wheel!"

So Kirishima got up to spin the wheel instead for Katsuki's turn.
