Hey, give him some credit here. He'd gotten a lot better at dealing with people in the time since they left home and all this weird shit started. Whatever, it made more sense to stay with what became familiar even if there were times it was weird as hell. The point here was, he'd only been especially irritable during their last few runs and Todoroki did a bulk of the talking even if he wasn't the best at it either. Yeah, yeah still more personable than he was, he got it.
The cold made him feel slow and it was harder to work up a sweat if he had to, which was the purpose of his gauntlets, not that he had them right now. Being sluggish turned him into a grump, nestled down into his collar while he walked close to Todoroki on his left side. He glanced over at the squeeze, pressing in closer to the other boy. The truth of it was, he wasn't as touchy as he used to be and it wasn't like their relationship was some secret and it was just a bonus that Todoroki happened to be warm. If he did suggest clearing the sidewalk again though, Bakugo might just bury him in the snow and leave him there.
At first he didn't think much of it when Todoroki let go of his hand, because he was probably going to be irritating as hell and clear the path anyway, so Bakugo kept walking and just slowed his step. Hey, Suki. Had it been anyone else that pelted him with a snowball like that, the expression on his face when the snow fell away would have spelled out certain death. "You're so fucking dead, Shouto!" The grin, even the threat wasn't quite filled with malice, but he sure as hell took it as a challenge. Kneeling down, he packed his own larger than necessary snowball to throw back at him, stepping off the sidewalk so there was a car parked on the street between them. "You caught me off guard, you ain't gonna hit me again."
