what is this feeling..

green-eyed monster

as izukus walking to aizawas classroom he thinks about how this all started. It would have to be at ground zero. After he was pinned to the ground after losing to Katsuki, and he felt an unexplainable warm feeling consume him. He still thinks about the look he received from Katsuki and it still makes him shiver with those butterflies.
After that day it was just a matter of tension and who would break it first. It was Izuku who first went in for timid peck on the cheek.. and up until now it was shy kisses or lingering touches and gazes... that was the first time they went that far

Izuku walks into the classroom, his face is only slightly flushed from the event that happened prior, and he avoids looking Katsukis way when a bubbly girl greets him. "H-Hi deku!"  Uraraka says moving so close to Izuku. She seems really nervous and her face is tinted red. Behind her he can hear Mina and Momo giggling. Confused, Izuku says "good morning ura!" and gives her a smile. She turns even more red, touches his arm and leaves it there, then gives him another shy smile. Once again a bit confused, but Izuku doesn't mind. That is until she moves so close to his face that she notices a hidden purple mark on his neck. "Hey deku, what's that-?".
Instantly turning bright red he jumps back embarrassed and yelps "o-oh it's nothing haha". More giggles from Mina and Momo and then the bell finally rings again signaling the start of class. As he walks to his seat his face is still red Uraraka keeps staring and smiling at him. Izuku sneaks a quick peek at Katsuki to see an annoyed look on his face. Hm. Well kacchan always pissed off about something.

- pov: Katsuki
waiting for the damn nerd to walk into the classroom he takes a few deep breaths. He trying to calm down his rapid beating heart. Just thinking about those forest green eyes and that mark and those hands all over him drives him crazy.
It was a big risk going that far. Asking Izuku to come with him into the bathroom then pinning him against the wall. He just heard something yesterday that pissed him off a bit..

-past:last night
He didn't meeaaann to ease drop, it's not his fault those girls don't know how to keep their damn voices low. While cooking for himself yesterday he overheard Mina asking  Uraraka why she seemed so blushie lately. And her response was a whisper that Katsuki had to strain his ears to hear. Apparently pink cheeks had a crush on Izuku. The moment she whispered that Mina broke out excitedly screaming. Smiling like a maniac she called over Momo, hakugure, jirou, tsui and a bunch of other girls from class 1-B. They all formed a circle and started talking about Uraraka crush on Izuku. Giving her advice, saying she should go for it, a lot of "I knew it!". But the think that set off Katsuki for a moment was when Momo said "He totally likes you too!". All the girls in the circle agreed saying "it's obvious", "you guys would be so cute!", "ura and deku sitting in a tree haha!".
The gross feeling in the pit of Katsukis stomach made him disgusted . It churned, leaving him a little empty and sad. So fucking annoying.

While recalling the taste of izukus lips he's snapped out of his day dream when he hears some girls giggling. Vibrant red eyes scan the room for the noise and land on Uraraka and Izuku talking. Fucking pink cheeks has her hand grazing his arm and a sickingly sweet smile are her face. Fucking batting her eyes. Then she gets super close to Izuku and he jumps back with a red face. Momo and Mina behind them "ooo"ing at the two. Uraraka probably said something that made him blush. So fucking dumb. Katuki roles his eyes ignoring the returning gross feeling. It's probably true, Izuku probably does like her back. I mean, he gets all red and fidgety around her. The way Uraraka looks at him is fucking disgusting, all smitten. Katsuki hates this feeling.
The bell rings and everyone goes back to their seats, she's still staring a Izuku from across the room so obviously. Aizawa says the class is all going to go do some hand-on-hands fighting and pairs us up in groups. Of fucking course Pink cheeks and the Nerd are in a group together, that leaves him with Momo.

-
walking towards the area where they were going to fight each other, Momo and Uraraka are whispering when out of nowhere she starts making flowers. The flowers come out from her chests are all different colors and she hands them to her. Uraraka places them at the corner of the arena. So random. She probably has some sappy plan in place.
Whatever, soon the real fun will begin.
-
Watching the other teams fight their was really only one person Katsuki was looking at. Can you guess who? His green hair was flowing in the wind and his eyes held a determined look the entire time, never faultering. Staring at the screen enamored look on his face, his hearts starts to thrum a little. He's pulled away from his intense staring when Denki jumps up onto his side. "Oooo kacchan your drooling haha! Who are your staring at huh?" Kirishima now on the other side of him says "Oh my god, you totally got a crush on Ururaka! You were staring at Midorya's team the entire time, that's so manly bro!".
Was he really staring that hard? The tips of his ears go pink thinking about the stupid face he was probably just making. "Ew what no, why would I like her?" He grits out
"Dude don't even try to deny it! The tips of your ears are red, your blushing!
Now officially pissed off he pushes the two away and shouts "dumbfucks".

-
now it was Katukis turn to go against some people, he goes against Asui and Oijrou, then Mineta and Hakugure, then finally, Izuku and Ururaka. She was clinging on to his arm chatting him up about some party they were going to have Friday. Katsukis eyes are full of intention set on Ururaka as the gross feeling returns. Then they quickly look to the side to meet an already staring Izuku. The moment their eyes meet for that one second sends electrifying sparks to his heart. His gorgeous green eyes will always be Katukis favorite color.
-"and START!"-
flying full force towards Ururaka first hitting and explosion the the front of her stupid blushie face the to the back of her head. Momos fighting with Izuku while Katsuki goes at Uraraka fully. Just looking at her dumb face makes him want to explode everything, so he does. He knows he probably is going to far, but it's to late. Sending a huge explosion down her way, he knows she can dodge it, she's very capable, yet still Izuku jumps in to save her and push him out of the way. The explosion sends everything close to them flying around, he burnt some of the flowers that Momo made for her, the rest are broken. When the dust from the explosion calms down you can see the full red face Ururaka is sporting. She thanks Izuku and tackles him in a full hug smiling. When she pulls out of the hug her face is still close to Izukus. Yeah Okay that's enough.
Yank.
He pulls Uraraka away from Izuku roughly. A confused and slightly upset Ochako looks up at Katsuki then shivers because he's giving her the scariest death stare you can imagine. Aizawa blows his whistle signaling the match is over and Katukis team wins.
Being the angel he is, Izuku offers to take Ururaka Recovery girl for the headache she got. And as everyone is walking out of the arena Katsukis spots something. It's green, and bright. It one of the flowers Momo made then he exploded, somehow this one made it out un-scratched. The color looks almost exactly like izukus eyes. A gorgeous flower. Katsukis picks it up.

Finally it was Izukus turn to fight with Katsuki and Momo. Though, the entire time he was basically just fighting agasint Momo. Oh Katsuki. He was going crazy, all he could think about today was what happened earlier, and how much he wants it to happen again. Just being close to him makes his heart beat faster. The out of nowhere theres a huge explosion targeted directly towards Uraraka and on insitinct he jumps up and pushes her out of the way. She thanks him with a hug, but stays so close his face it makes Izuku a bit uncomfortable. That's why he's sort of glad when Katsuki rips her apart from him. Looking up he sees Katsuki giving a terrifying look to Uraraka. After the whistle is blown he offers to take her to recovery girl and they start walking out. Uraraka won't stop chatting, and Izuku feels a little sick.
