Slight Angst?
Kirishima and Bakugou are dating and everyone is happy for them(except Deku because...you know...reasons)
But one night, Bakugou goes to Kirishima's room to give him his surprise since it was their anniversary...but when he gets to the door he hears moaning...
He slams open the door to see Kirishima in bed with XXX(pick whoever you want but it's a guy)
Bakugou starts crying and yelling causing everyone to run up to the sound and see what he sees...
Bakugou runs off and the BakuSquad is being held back by the others so they can't...talk to Kirishima and XXX
But no one notices that someone is gone...
Time Skip
Bakugou is in a tree crying his hear out and holding a little red box(no it's not a wedding ring but a promise ring)
He opens the box and stare at the ring for a few seconds, before throwing it to the ground and putting his head in his arms
Down below someone picks up the box and looks up
"Kacchan." Deku calls to him
Bakugou holds his head up and looks down, to see Deku with the box in his hand and his eyes shining bright in the moonlight and showing sympathy and...something else?
"W-what..." Bakugou says voice cracking
"Come down." Deku says
Bakugou shuddered...He never heard Deku use that tone of voice before...
He stood up to climb down but... his foot slipped!!
"KACCHAN!!!" Deku screamed fear in his eyes
THUD
Bakugou had his eyes closed waiting for the pain but he never felt it...
He opened his eyes to see...Deku holding him princess style!!!
"Are you okay, Kacchan!?" Deku asked eyes full of concern and slight tears in his eyes
"I-I'm okay!" Bakugou stuttered face red
"I'm glad." Deku smiles softly
It was like time had stopped...they didn't even realize they were slowly moving closer to each other...eyes going half lidded...
Their lips touched...
After a few seconds, they pulled apart, eyes opening slowly
Deku smiled softly and Bakugou did the same
"Let's go back." Deku said turning around and walking back to the dorms
Another Time Skip
Everyday, Kirishima would try to talk to Bakugou about what happened and apologize saying it was a accident but Bakugou didn't want to hear it and neither did the Bakusquad or his other classmates
Till one day
Bakugou was early, standing by the window looking out. When he heard the door open and Kirishima standing in the doorway.
"Kat..." Kirishima whispered
"Don't call me that!!! You have no right to call me by my first name!!!" Bakugou growled glaring at him
"Please Kat!!! It was a accident!!! I didn't mean to sleep with him!!!" Kirishima says walking to Bakugou
"Yeah right..." Bakugou growled turning his head
Kirishima was right in front of Bakugou and he could see Bakugou's shoulders shaking...he was crying.
"Kat...I'm really sorry... I really do love you." Kirishima says grabbing face and turning it towards him
"You have five fucking seconds to get your filthy cheating hands away from my baby or so help me..." A voice behind them growled
Kirishima turned around to see Deku and the others standing behind him. Deku walked more like stomped over to them and ripped Kirshima's hands away from Bakugou and pulled him to his chest with his arms wrapped Kacchan's waist
"Wait...dont tell me...you two are..." Kirshima stuttered looking between the two
"Yes Kacchan and I are dating. So you can go be with that bitch you cheated on him with." Deku growled pulling Bakugou tighter
Kirishima glared at Deku and vice versa it was a tense atmosphere. Everyone was too scared to move until...
"Izu..." A soft voice whispered
Deku immediately turns his head to Bakugou and smiled
"Yes baby?" Deku asked cupping Bakugou's cheek
Bakugou nuzzled into the hand, eyes closed then opened them
"Don't worry about him. He's not worth you're time, besides...you already won." Bakugou whispered against Deku's mouth
Deku leaned forward and the two had a passionate kiss right in front of everyone
Kirishima's heart shattered...but he couldn't look away
Deku opened his eyes and locked them with Kirshima and he smirked into the kiss and slowly moved his hands towards Bakugou's butt and squeezed
"Deku!!! You pervert!!!" Bakugou growled blasting him in the face and running out the class
"Kacchan!!! I'm sorry!!!" Deku called out running behind him
But before that he whispered in Kirishima's ear
"He's mine now. And if I catch you near him again...I wont hesitate to END you." Deku said smirking eyes flashing a bright green before fading
