"Your hand is f*cking cold, Todoroki!"

The three of them were holding hands all in a row on the way home from Kiri's Manly Christmas party, forming a blockade of gross PDA stretching across the sidewalk. Bakugou was in the middle, with Todoroki on his left and Deku on his right.

"Sorry" Todoroki says, loosening his hand from Bakugou's.

Bakugou slightly panics when he feels his boyfriend's hand drop, but his pride won't allow him to take back what he said. He squeezes Deku's hand before letting go and quickly grabs Todoroki's other warmer hand before he can pull away further.

"Hmph! It's not a problem like this, right?" He asks, turning his head away.

They wait for Deku to pull on his gloves before lacing his fingers through Todoroki's cold ones. He doesn't like having stiff fingers. Todoroki can't help but look at the gloved hand worriedly.

Deku tugs on Todoroki's shirt with his free hand signalling for him to lean down. "You know I love both halves of you, right?" he whispers into Todoroki's ear. Deku then pokes his head out in front of them as they walk, wiggling his eyebrows for Bakugou to say something too.

"Like I'm going to be outdone by Deku of all people…" he mutters. "Look," he drawls loudly, "Biology is biology. I don't care which half of you your shitty parents loved better. Your right hand is f*cking cold. Who wouldn't like to hold the warmer hand in this f*cking cold weather?"

Deku giggles. "Look, Kacchan admitted he likes holding your hand."

"I DID F*CKING NOT! I'M GONNA F*CKING KILL YOU DEKU!"

"Eep! Hide me Shoucchan!" And they dart forward and back, around and behind him, tugging him every which way but not letting go.

The next day, when they go to visit Inko, Todoroki offers to take the spot on the right.

"Are you sure?" Deku asks.

And Todoroki nods. "I know you love all of me. And I love all of you guys too."

/Notes: Originally an OT3 headcanon, but some person took it the wrong way that I don't love todokidoki enough? Like chill, it's just a headcanon. Anyway I wrote a little thing in response. Original HC: Todoroki is only allowed to be on the right side when they hold hands. They tried it with him in other positions, but Bakugou complained it was too cold, and while Izuku didn't say anything, he silently put on his gloves before taking Todoroki's hand./
