You're a class 3-A student. You've been friends with Izuku Midoriya for quite a while now. You aren't very similar, and don't have that much in common, but still get along quite well, both being interested in quirks. You're still optimistic and adventurous, but you're more on the blunt, irritable side. Anyhow, you two are close friends, even physically affectionate sometimes. Though you find his shyness annoying sometimes, you like him a lot nonetheless, for his hard work, etc., and he admires you, because he puts you on a high pedestal, due to your techniques, strategies, whatnot. Right now, you and your class were in the common room, and he was taking notes on your quirk, just more detailed ones than he'd taken before based on his observation. Izuku spoke, his gaze remaining on his notebook as he wrote speedily, determined and focused,

"What does your cool off time depend upon?"

You thought for a brief moment before answering,

"Well, the cool off time in minutes after a long distance is the distance in kilometres multiplied by eight and divided by ten, I mean, approximately, at the very least."

You had studied your quirk in detail of course, and some others which you were interested in so answering these questions was an easy, peaceful task. Though then Izuku asked writing,

"How big is it?"

You, being in the flow and mode of answering the question without a thought (due to your focus on remembering the answers and replying in a precise way, plus you trusted him), so, you replied,

"Eight point one inches."

Izuku wrote, then you paused, realising what just happened, and flushed slightly in embarrassment,

"Wait a minute! Why did you ask that, and how is that relevant information!?"

The Izuku you knew was supposed to be pure, innocent and shy, how could he just-

"Oh, um, Denki asked me to ask you so I did-"

Izuku replied, not realising what the question meant, Denki was chuckling on the couch, Kirishima, Mina, Sero were trying not to, Iida, Uraraka, and Momo looked flustered.
