"DEKUUUU! Just you wait, I'm gonna crush you, you fuckerrrr!!" screamed Bakugo.
"No, I will surpass you for sure, Kacchan!" Deku yelled back. "You're in for a surprise if you think you're going to beat me that easily!"
Bakugo glared at him. "Oh yeah?"
"Yeah!" Deku defiantly shouted back at him. "Just see what you think of this move!"
And he was running towards Bakugo. He needed to be precise if he wanted to do this without injuring himself in the process, which was almost impossible as it was. They were on a training field, fighting one-on-one in All Might's Basic Training class. And Deku was pulling out his ultimate move. He was 100% sure that it would stun everybody, including and especially Kacchan. But he was also sure that this was how he had to tell him. With his one, Ultra Power Undefeatable Smash Move. He knew from the beginning that with this one move, he'd gloriously defeat Bakugo. How, ladies and gents? Well, it went a little like this —
As Bakugo was about to smash his flaming fist into Deku's abdomen, Deku jumped and closed the distance between them, grabbing Bakugo's collar. Now, this was the tricky bit. The actual move had to be perfect. So he kept his face a safe distance away as he pushed Bakugo to the ground, only leaning in right before they fell.
"Mmph!"
With that, Deku knew he'd won. He'd gotten Kacchan, after all this time! He'd left him speechless! But that was only step one. He had yet to make Kacchan his, for real. Deku felt his soft lips, and couldn't resist sighing a little, tilting his face and pressing himself closer. Kacchan wasn't moving at first, but when he felt Deku's lips moving against his he automatically kissed him back, opening his mouth a little when he felt Deku's tongue on his lips, and groaning at the feeling of his tongue slipping past and brushing the roof of his mouth, and God it felt so good for some reason —
And then he realized that he was kissing Deku. His first instinct was to shove him away with a gasp, blushing madly. There was a silence. All their classmates stared, shell-shocked. Since Bakugo had pushed Deku backwards, there was no place for Deku to go except sit up, because he'd fallen on him previously, and now he was straddling Bakugo, amused, watching his bright red face carefully. After a while, Bakugo spoke.
"Wh-What the HELL was that?!" he yelled, but somewhat shakily. Deku grinned sheepishly at him.
"Well, I did tell you you were in for a surprise..." he mumbled. But his beloved Kacchan was downright glaring at him now.
"Why did you do that?! It's not funny! You think it's funny, don't you! It's not a joke for me!!" Bakugo huffed, giving Deku another shove and standing up.
"Kacchan, wait, that's not what I - " Deku tried to speak, but Bakugo had already started running back to the classroom. Deku sighed.
"Great," he mumbled, getting ready to chase after him, when he felt a sturdy hand on his shoulder. He turned, and All Might was sobbing.
"Oh, M-M-Midoriya-shounen, I was looking forward to saying "Good for you!" but...and when you finally tried to tell him...UWAAH, I'm so happy for you, but you need to clear up this misunderstanding," All Might cried. Deku raised an eyebrow.
"A-All Might...you're not the one who should be crying..." he murmured, but then felt a shove.
"Iida-kun! What was that for?" he frowned.
"You must hurry, Midoriya-kun!" Iida said. "Bakugo is surely feeling angry and upset. He might not even listen to you! Quick, clear it up, there's no reason for either of you to be miserable," he said earnestly, pushing his glasses back. Deku nodded, a bit stunned.
"R-Right." he murmured, and took off to the building.
"Kacchan!"
After some searching, he found Bakugo in their empty classroom. He looked up from where he was sitting on the floor, under a window.
"What do you want, you bastard." he grumbled. Deku sighed.
"Sorry, Kacchan. Maybe you won't like what you'll hear," he started, crouching down in front of Bakugo to lift his hands off his face. Bakugo was already glaring at him, but his cheeks were red and he was tearing up a bit.
"...but I like you, Kacchan. I've always liked you for a long time," Deku mumbled, blushing. "So it wasn't a joke for me either!"
Bakugo just stared at him. Then a tear spilled out of his eye.
"Sorry, Kacch - " Deku started, panicked, but was silenced when Bakugo pulled him closer and threw his arms around him, squeezing him tightly.
"Kacchan..."
"Shut up."
"Kacchan, does this mean that you also li - mmph!"
Bakugo pulled back to kiss Deku, smashing his lips to his to make him shut up.
"I told you to shut up, Deku," he mumbled, hiding his face in Deku's shoulder. Deku laughed. And then he heard a tiny whisper.
"I like you a lot..." mumbled Bakugo. "So much that I don't know what to do."
Deku's heart fluttered.
"Then I guess you have no choice but to be with me," he whispered back. Bakugo blushed.
"I-It's not like I'm submitting to you or anything!! I'm not giving up, I will be stronger than - "
He was silenced by a long, soft kiss from Deku, and grabbed onto his shoulders, digging into his skin with his fingernails, gasping softly.
"It's fine. You don't need to. We'll make each other stronger, okay, Kacchan?" he said with a smile. Bakugo pushed him away.
"Sh-Shut up," he grumbled.
