Katsuki Bakugou Ao3 fics

A Study In Deceit by; mentallypapaya

Another papaya work, only the first chap go read the rest on AO3 it's great trust me

Summary:

Katsuki was a smart kid, that much was obvious. What wasn't so obvious was that he was much smarter than he ever let on.
He always kept his mind and talents close to his chest, content to sit in the background and observe. So what happens when somebody claims to see passed his dumbed down mask? What happens when they want him to show off a bit more?
As the situation slowly gets more and more dangerous, Katsuki has to decide just how far he'd go to keep his skills to himself, and how far he'd go to protect his classmates.

I watched the entirety of BBC Sherlock in one week and now we're here

Chapter 1: Prologue 1

Aizawa was annoyed. That was interesting.

Katsuki leant back in his chair, ignoring the worksheet in front of him in favour of scanning over his teacher's body language. It was fine, he'd finished his work within the first two minutes of being handed it. It was dreadfully boring, stuff he'd been able to do since he was three. He'd much rather spend his time entertaining himself by reading his teachers and classmates, it was more of a brain exercise than any of the other bullshit he got taught in this school.

Katsuki narrowed his eyes slightly, flicking his eyes over where his teacher was sat at his desk silently, before looking away and focusing on his fingernails as he thought. It was always fun to see how much he could get with only a few seconds of observation.

Aizawa was obviously annoyed about something, he could see it from the tense shoulders and occasional slight downturn of his lips as he thought over whatever was pissing him off. He always caught himself a few seconds later and forced his face to go back to normal, though.

So it's a private matter, one he doesn't want anybody in the class to take notice of.

He was also fiddling with the wedding ring on his finger.

It was a marital argument, then. Fascinating.

Honestly, Katsuki had no idea how nobody else in his class had caught onto the fact that Aizawa and Present Mic were married, he thought it was perfectly obvious. They had the same brand coffee stains for crying out loud!

As far as Katsuki could tell, though, the two didn't have many arguments, or at least not ones that bled into their work life. What sort of disagreement would leave Aizawa so testy during class? He flicked his eyes upwards to scan over his teacher once more.

His eyes locked onto few tiny white spots on Aizawa's jacket. Small pieces of tissue that had seemingly stuck to his clothing. Bingo.

Aizawa was somewhat of a neat freak, surprisingly. He liked his clothes to be tidy and his things to be organised. That much was obvious from the strict way he kept his desk, and the way he would unconsciously smooth out the creases on his clothes while standing. Present Mic, however, was a much more forgetful and messy type of person. It was clear from Katsuki's observations that it was one of the weaker points in their marriage. They loved each other a lot, but the way Aizawa's lips would thin whenever Present Mic would get crumbs everywhere while eating was damning evidence towards their home spats.

Thinking back towards yesterday's observations, Katsuki smiled to himself, making a deduction.

Yesterday while walking to the dorms Katsuki had managed to notice Present Mic blowing his nose and shoving the tissue into his pocket. Now, most people would throw the tissue away the second they came across a bin, but like he said, Present Mic was very forgetful. If he had forgotten to take the tissue out before putting his clothes in the wash with his husband's own clothes..... it would have made a mess. Aizawa expecting to find his clothes all nice and clean and instead finding them covered in shredded tissue would definitely be enough to cause this current bad mood.
