Bakugou was never the exceedingly possessive kind (as surprising as it may come to others), because he understood the feeling of someone thinking they have some sort of hold on you and thinking you were their show off trophy. He hated those people who always kept their significant other close, too close, and shoved away anyone else.
Partially also because he knew that Todoroki hated it — the unhealthy possessiveness of his father or fend for himself attitude, whatever it was it wasn't Bakugou's business — and so he simply granted him that.
People had questioned it at times, and Bakugou had rolled his eyes at them.
He never felt jealous, or insecure, or possessive; because he knew unlike all the things he had to fight tooth and nail for, Todoroki was indisputably his and his only. That fucker would bring him rocks for fuck sake, like he's gonna bat an eye for someone else.
It was all the same until the chemical engineering charmer Sakura came into the picture — a win all your hearts attitude with a pretty face to go along with it — it took her a day max before all the boys in the class were following after her like a bunch of starstruck children.
Bakugou rolled his eyes as she ruffled this dude's hair, making him melt at spot.
“Oi look.” Kirishima nudged him, thank god he was the only one immune to her charm or maybe he's just gay as fuck like him, jerking his chin towards the classroom's door. Bakugou felt his heart flutter at the sight of Todoroki, dressed in simple jeans with Bakugou's hoodie he had sagged this morning and holding two coffees, looking like a lost puppy as he searched the room until their eyes met.
He immediately skipped up the steps to meet Bakugou and Kirishima in the back of classroom, giving his usual tiny smile. “Hello.”
“Hey, Shou.” Bakugou said, grinning at his boyfriend's mishap hair. Gosh he probably woke up late again and rushed here.
“Hi Todoroki!” Kirishima waved.
“I brought coffee for you two.” Todoroki said as he set the two bobas down, handing down the straws. “Honeydew extra sugar for Kirishima-kun and Matcha with skimmed milk and no sugar for Katsuki.”
“Dude you're a blessing.” Kirishima grinned as he slurped his tea with a sigh of content. “Thank you.”
“You're welcome.”
“Hey icyhot, when does your class starts?” Bakugou asked and Todoroki's expression stilled, he blinked at Bakugou as he whispered a quiet aw fuck under his breath; could somebody be more clumsy. “Go before your professor yells at you.”
“I will catch you later, bye.” Todoroki promised and gave Bakugou's hand a little squeeze. He waved them another bye before running out of the classrom, narrowly dodging the professor that was entering. Bakugou chuckled.
His mood was easy until his eyes met Sakura, as she watched with a look on her face that he immediately put at the top of the things he hated.
###
And turns out he was right.
It was easy for Todoroki to catch eyes of others, he was a whole package of everything good, and all almost everyone on their university grounds knew him. One of the top students, most handsome face of the university for three years, the volleyball team setter who held the best setter award, and also son of the trustee (ew) but nonetheless Todoroki was a eye candy.
Bakugou entered the library to the sight of Sakura leaning against the table where Todoroki was sitting and chatting him up — the boy however look complete uninterested and thank god — she cheesily nudged Todoroki and giggled.
“Shouto.” Bakugou said, his voice seemed chilly to even himself and Todoroki perked up at his presence. “Done with your classes?”
Before Todoroki could answer she quickly interrupted, slinging her arm around his boyfriend like they were bestie for life or something. It made eye twitch but he said nothing, there was no point on screaming and plus he didn't want to make Todoroki more uncomfortable than he already looked.
“Bakugou, we share the same class together.” She smiled, resting her chin on Todoroki's shoulder and he squirmed a little. “What major are you in?”
“None of your business, is it?” He snapped and grabbed Todoroki's wrist yanking him up. “Now if you'll excuse us.”
“Aw don't be a stuck up.” She stood and brushed her hair behind her ear. “There is a party today, why don't you come as well?”
“No shit, I'm busy.” Bakugou said.
“But Todoroki will be there, so I assumed so will you.” She batted her eyelashes innocently as Bakugou gave Todoroki a seething stare.
“It's Asido's party. She invited us remember?” Todoroki titled his head in innocence. And ah yes she had.
“This is great!” Sakura grinned and rubbed her hand on Todoroki's arm. “We can have some fun, right Todoroki-kun?”
She winked and walked away.
Todoroki turned to Bakugou with a worried expression.
“Are you busy tonight Katsuki?” He asked. “You had said yes the other day so I thought you would be going.”
“Argh yes I'm going icyhot.” Bakugou said, like hell he'd leave this social misfit in the hands of his even more socially disastrous friends. “Now let's study, chemical engineering isn't easy.”
Todoroki giggled and fuck this might turn into a make out by the end of it. “Okay, I need to do some notes as well.”
###
Katsuki glared at Sakura's attempt to flirt and touch Todoroki as the boy tried to get himself some drinks. She even tried to snake her arm around his waist but he took a little step back, giving her a warning look.
“You chill dude?” Kaminari asked as he followed after Ashido and Sero on the dance floor.
“Yeah, just need to put someone in place.” Bakugou spat and Kaminari looked over to where Sakura flattened Todoroki's shirt with a suggestive stare, giggling about something and the sight made both of them wince.
“Show her who's the competition here.” Kaminari winked as a Kirishima called for him for another rounds of shots. “Gotta go dude, and don't worry. Todoroki ain't got eyes on anyone but you.”
Bakugou smirked. “Yeah, I know that.”
Todoroki finally shook off Sakura and came back with drinks in his hands, giving Bakugou an apologetic look.
“She is ... persistent.” Todoroki mumbled in distain as he handed Bakugou the drink and he downed it in on go.
Before Todoroki could sit, Bakugou easily pulled him onto his lap, letting him sit sideways and into a snug position with one leg over the armrest. Todoroki made a soft sound of surprise, barely saving his drink from spilling all over him, he then proceeded to give Bakugou a pouty look.
“What was that for?" He asked and Bakugou took the drink out of his hand and kept it aside, he doubted Todoroki would be able to save it again. “Katsuki?”
“Can I kiss you?” Bakugou asked, eyes fully focused on Todoroki but he could feel Sakura's stare on them — that's right, see who he belongs to.
“Y-Yeah, of course.” Todoroki answered with a frown, probably wondering where all of this was coming from. Bakugou quickly closed the distance between them, liking how Todoroki quickly melted into him with eyes fluttering close; shifting a little so that he was kissing him better.
Yes, no one would ever get him breathless like Bakugou would.
Mine, he's just mine.
Todoroki's breath stuttered when Bakugou slowly rubbed circles on his inner thigh, closely moving up and unfolding his boyfriend with ease. He took care to make eye contact with Sakura before he shoved his tongue down Todoroki's throat and made him moan, giving one of his most arrogant expressions.
She glared at Bakugou with full force and dumped her cup onto some poor dude who was flirting with her, stomping out.
“K-Katsuki.” Todoroki was breathless when he pulled away, flushed deep and eyes hazy.
“Who do you belong to?” Bakugou asked as he kissed up Todoroki's neck and sucks at his soft spot, making him whimper and squirm in his arms. “Tell me, Shouto.”
“You.” Todoroki's said breathlessly. “Only you.”
And Bakugou would show that to anyone who messed with him.
