Red string of fate but only one person can see it.

Some people lie and say they see it when they don't

Some people hide the red thread

Some people suppress their feelings until it comes out explosively and then shout in the middle of class, "YOU'RE MY SOULMATE SHITTY DEKU!"

The whole class spun around and stared with their jaws dropped open.

"Ka-Kacchan??"

"Bakugou, sit down and talk about this after class."

His face burst into a blush and his hands started sparking. Aizawa's hair flew up and he forced Katsuki to sit, silencing his quirk.

"Later."

"Whatever."

He could see Deku jittering in his seat and his nerves bubbled in his stomach. What if he said no, what if he didn't believe him, what if he just wanted to be friends?

So many what ifs swirled around his mind he didn't even notice when class ended.

"Eh... errrr... Kacchan?"

"What do you want?" He spat instinctively.

Deku jumped and he immediately regretted raising his voice.

"Shit, don't be scared."

"I'm not scared of you Kacchan... not anymore."

"You're my soulmate."

"Kacchan I um... Are you sure?"

"Yes."

"How?"

Katsuki gave a hard tug on the red string connecting them and Deku fell forward. He caught him easily. Deku held onto his biceps and looked up at him with big eyes.

"We, we are..."

Katsuki wrapped his arms around him, crushing him slightly

Deku wheezed and Katsuki set him down anxiously. "Didn't mean to hurt you."

"I'm fine Kacchan..."

Silence.

"Kacchan, umm..."

Katsuki leaned down and bumped their mouths together clashing their teeth. Deku eeped and they pulled back.

"Shit, fuck I-"

Izuku got on his tip toes and pressed a closed mouth kiss against his mouth. "Um..." His voice was at least an octave higher. "I'm sorry."

Katsuki snaked his arm around his waist and chuckled before pressing a real kiss on his mouth.

Deku hummed into the kiss.

Resting his palms on Katsuki's chest. They separated for a few seconds before the magnetic attraction brought them back together.

They separated and nuzzled foreheads. "Is this really happening Kacchan?"

"Yeah nerd."

Deku began to cry making Katsuki wonder wtf he did wrong.

"I never thought... I never imagined you would feel the same way."

"Well believe it." Katsuki said kissing his forehead.

"Hai."

"Cause you're mine."

"Hai."

"And I'm yours."

"Hai," he whispered as their lip met again
