Genya x Shy Reader

This is written as a female s/o since it's easier for me to write I hope that's ok. For this Genya and reader are both 18 in their senior year so slightly aged up Genya and Co.

-You were the newest student in Kimetsu Academy, just transferred over from another school when your parents moved you closer to your father's workplace. You weren't too nervous. Some of your friends went to the school so it's not like you wouldn't go in not knowing anyone. However your first day was anything but a good start.

-First you were really late because your mom's car got a flat tire on the way to driving you there. Then you dropped your coin purse containing your lunch money outside while you were rushing into the school. A teacher happened to have noticed that you dropped it but you didn't hear him calling out to you. Then you got laughed at when you busted into the chemistry class (which was the first class you had) and got both laughed at by a lot of the other students and chewed out by Professor Obanai for being late to his class. Then when lunch came around you had to sit down and go hungry except for some spare things given by your friends because you didn't have money or brought your own lunch. Just when you think it couldn't get any worse too-

-Sanemi, the scariest teacher in the entire School even more than Professor Obanai, had just roughly pushed the door to the cafeteria open and his narrowed eyes scanning the area until they lasered focused on you. "HEY YOU!" The entire place silences immediately terrified at the sounds of the scary man's voice. "NEW GIRL!!" You feel yourself freeze up on the spot as the heavily scarred man comes marching up towards you looming over your terrified form before a cute teddy bear themed coin purse is roughly pushed into your shaking hands. "I've been trying to fucking track you down all day! Don't forget your purse outside again!"

-Its cannon in Kimetsu Gauken that Sanemi likes kids and respects women but most are scared by his appearance and honestly sometimes he comes off as scary without meaning too. Sanemi honestly wasn't trying to scare you, he was genuinely just trying to return your purse to you but he wasn't socially aware enough to realize that calling out a trembling girl in the middle of everyone and looming over her scared you so much that you became very scared of your new math teacher.

-It was around the second week you were there that you learnt one of your fellow students was the younger brother of the scary teacher. From the first day forward whenever you had math class you kept your head down and very quiet to avoid him singling you out but today was study day before a big test so everyone was partnered up. "Kanao get with Inosuke! Kamado's with the blonde kid! New girl go get with my brother! All of you take turns asking questions with these flashcards! All of this will be on the test tomorrow so PAY THE HELL ATTENTION AND STUDY!"

-Your pupils shrank in fear and a rock fell in your stomach. Brother? Mr. Sanemi had a BROTHER?! As soon as Genya sat down in front of you holding the flashcards for your shared study session, you knew without a doubt they were related. Their faces were similar shaped especially their eyes, and like a brother he also had scars on his body although a lot less than Sanemi did. As soon as Genya saw your big doe eyes all shiny and pretty looking up at him, the baby boy was smitten.

-He's had crushes before. He's had fleeting crushes on both his friends Aoi and Kanao before they gotten into relationships with his other guy friends and when he was younger he always thought Ms. Kanao was the prettiest girl ever, but after seeing you he gained the biggest crush in his life that it felt like Cupid smashed his head with a mallet of love.

-It then started a cycle between you two. He started to try and approach you. "Hey! New girl!" You freaked out by the sudden repeating appearance from him. It was bad enough the teacher seemed to be annoyed with you but did his brother have to harass you too?! You kept running away from him or had your friends block his way to you until he left or you escaped. He was hurt you seemed to be so scared of him and for the longest time didn't have the foggiest idea why. He tried getting Tanjiro's help in convincing you to hang out with him in a group setting to see if maybe he could ease your worries by having other people around but you always asked if Genya would be there and Tanjiro...Well he's an awful liar so even if he said no you knew otherwise and declined.

-Then one day while reading it hits him. Your very first day the week prior to meeting Genya. Sanemi returned your purse and you seemed terrified of him. I'm turn it must've made you genuinely afraid of him as well. That day when Genya gets home he literally kicks down the doorway startling his mother, Sanemi, and their younger siblings with his anger. "SANEMI WHAT THE FUCK?!"
