Bakugou hated parties.
His old hag had insisted he socialize at his new university, and his cousin Deku had dragged him along, promising this party would be better than the last. It most definitely wasn’t, and the damn nerd had abandoned him to chat with a bubbly brunette shortly after they arrived.
Bakugou didn't care to suffer through small talk with any of the people here he deemed "extras", so he grabbed a beer and found a wall to lean against by the bathroom. As he swirled the bottle of bitter liquid, he allowed his head to thump against the plaster behind him. It was well past his bedtime, and he closed his eyes, wishing he was at home asleep instead of here at this too loud, too crowded college party.
Some loser that had drank more than they could handle stumbled through the hallway and into the bathroom, barely making it in time to vomit in the toilet. Fuck this, Bakugou decided as two more extras ran down the hallway to check on their friend. He pulled his thin leather jacket over his shoulders and stomped towards the front door of the high-rise apartment.
He was annoyed to spot Deku in an animated conversation with the brunette from earlier, now joined by the owner of the apartment, some trust fund kid with red and white hair. They were in the way, of course, and there was no possible path to avoid them. Shit. If his cousin saw him trying to leave, he would beg him to stay and Bakugou did not want to deal with that.
Changing course, he began looking through the windows to find the dark metal staircase he had seen outside the tall building earlier. Bakugou had to get out of here, and he could make a covert exit using the fire escape. There. Glancing around to make sure no one would notice, he opened the window and started to swing himself outside.
"Hey Blondie! Whatcha doing?" He heard a curious and unfamiliar voice ask from behind him. Fuck. He had been caught.
Bakugou, irritated he was unable to sneak away quietly, growled in frustration. "What the fuck do you ca-?" But the question died in Bakugou's throat as he turned to confront the stranger, only to find himself face to face with the most attractive man he had ever seen.
He wore his red hair in spikes and a crooked grin allowed Bakugou a glimpse of sharp white teeth. A thin scar ran down from his quizzically raised eyebrow to the top of his cheek, accentuating his ruby eyes. A Crimson Riot shirt fit snuggly across his broad chest, and the rolled-up sleeves of an open checkered button down showed off his forearm muscles. Tight dark blue jeans hugged his thick thighs and calves, frayed cuffs ending on a pair of black Converse.
Bakugou t’ched and turned away, feeling a warm blush creeping into his face.
The red head chuckled, "You know, this place has a perfectly functioning front door.”
"I'd rather leave this way." he grumbled, but hesitated, staying poised on the ledge with one leg already hanging outside. Bakugou blew a puff of air out of his cheeks and turned back towards the handsome stranger. "You should come with me and get some fresh air. This party smells like sweat and desperation.”
The man’s shark tooth grin grew, and he reached a hand around to the back of his neck in an awkward yet endearing motion. “Sure thing Blondie, sounds good!”
Bakugou swung himself out fully onto the platform, a small metallic rattle ringing through the cool night air.
“Don’t call me Blondie, Shitty hair.”
"Shitty Hair?” He gasped, reaching up to twirl a red tuft between his fingers, “My hair's not that different from yours." The stranger landed with a thud behind him, having jumped with both feet. "The name's Kirishima!" he proclaimed while pointing his thumb at his broad chest. “What’s yours? Since I can’t call you Blondie.”
He rolled his eyes, but couldn’t help the slight uptick of the corners of his lips. “Bakugou.”
It didn’t take long to reach the bottom of the stairs, but the ladder that would allow them to climb to the ground was pulled up, and stuck. "Dammit!" Bakugou cursed, shaking the ladder uselessly. Staring at the concrete below, he wondered if he could jump down from this height. He was reckless, but decided it wasn’t worth the chance of breaking an ankle.
"Why don't we go to the roof? It's a nice night and it'll be way better than going back to the party!” Kirishima didn’t give him the chance to answer before grabbing his hand.
"Hey!" Bakugou protested, almost tripping over his combat boots as he was tugged up the fire escape, past the window they had come through and all the way up to the top of the tall building. Upon reaching the roof, Kirishima released Bakugou and sat down, leaning back on his hands and laughing loudly, the sound musical. Bakugou felt another blush rising and tried his best to force it away as he sat next to the boisterous red head. Kirishima tilted his head back and stared up at the sky, a quiet sound of awe escaping his perfect lips. Bakugou stared at his profile for a few seconds before leaning his head back as well.
The sky was beautiful, deep blue and cloudless, littered with bright pinpricks and a waxing crescent moon. Up here, above the pollution of the city, Bakugou was reminded of his favorite mountain view.
"Stunning." Kirishima stated in wonder from beside him.
"Yeah, it is."
"I wasn't talking about the sky."
He turned towards the red head to discover he had bridged the small gap between them. Ruby eyes stared into crimson for a moment before dropping away. "I noticed you as soon as you walked into the party." Kirishima confessed, cheeks warm as he traced around Bakugou's fingers, splayed on the concrete.
"You looked so gorgeous with your eyeliner and leather jacker. Hell, even your scowl was sexy. I had to talk to you, but you disappeared. I thought I’d missed my chance. Then I found you, climbing out through the window, and, well . . . " He connected their eyes once again, "here we are."
"I want to know you, Bakugou. I want to know what makes you smile, what excites you . . . " Leaning closer he brushed a lock of blonde hair behind Bakugou's ear, and he shuddered as Kirishima’s warm breath tickled his cheek "what makes your heart race." Kirishima pulled back slightly, his eyes flickering between crimson eyes and softly parted lips. "Stay with me tonight, under the stars. Stay with me, and tell me everything."
Bakugou gave a small nod before closing the space between them. The kiss was soft and slow, mouths slotting against each other as hands held warm cheeks and arms wrapped around strong bodies. Kirishima took the blonde's bottom lip between his teeth and tugged gently. Bakugou moaned, and the red head used the opportunity to deepen the kiss, sliding their tongue together. They took their time, kisses fading to short pecks and pressed foreheads.
"I’ll stay with you, Kirishima. I want to know everything about you too.”
Kirishima sealed their lips again. "I'll tell you anything you want to know."
They stayed together all night, learning about each other in more ways than one, and Bakugou was gone, a hopeless romantic falling in love with a stranger on a rooftop, feeling thankful for bad parties and fire escapes.
