A couple weeks later, Senji started taking some time during work to spar with Bakugo. The nature of their scuffles meant they had to work out in the yard, where the heat was hard on her. She went all in, just as she promised before the study sessions. As much as she hated it, Bakugo was a pretty decent teacher. With that in mind she wanted to make sure to train him well, even if it meant potentially giving him an advantage against her. His movements were rough, but he did learn quickly. Finally he was able to win one of the matches, pinning Senji into the grass.

"Ha! I win!"

"Yeah," Senji was nearing her limit from the sun beating down on her. Bakugo noticed, but said nothing and released her. He decided they were done for today and headed inside. Senji followed behind him and prepared for the rest of her cleaning. She moved laundry over to the dryer, then headed upstairs to work there. Once finished, she gathered the supplies she had used and headed down. Bakugo skulked through the house doing his own thing while she worked, gloating occasionally.

Senji heard him sneer as she neared the bottom of the stairs. The items she carried weren't particularly heavy, but she was starting to struggle with them. [Shit.] Her body grew hot, then cold. Her vision clouded, and she felt herself falling forward. She had messed up by being outside too long, on top of her already busy schedule between differing assignments. The fatigue caught up with her in an instant, and just before the last step her legs gave way. She fell hard onto the floor and the bottle of cleaning solution she had burst open. Some of it splashed onto her arms and shirt.

"Hey, what the hell?," Bakugo, who had just witnessed her fall, stopped short.

"Sorry, fell. It's fine," Senji pulled herself up, cursing under her breath. She started picking up the items she'd dropped, but her movements were stiff and strained. Bakugo noticed that where the solution had touched her skin was turning bright red, like burns.

"Go get that off your skin. Shower."

"Huh?," Senji did a double take.

"Go shower, that's burning you isn't it?," Bakugo knelt down and scooped up the now half-empty bottle. He practically shoved her back upstairs, leaving her dumbfounded in the bathroom and shuffling off. Senji was stunned, but only for a moment. The cleaning chemicals really were burning her skin, and the pain made her wince. She peeled off the soaked shirt and started the shower. It took her a few minutes of fiddling with the controls to get the water going at a comfortable temperature. The door opened behind her, startling her.

"Hey-!"

"Shit. Here."

Bakugo threw a bundle of extra clothes at her and slammed the door shut. Senji was once again completely stunned, and a little embarrassed. She stepped under the warm water, processing her thoughts there. No matter what she arrived at, it was clear that Bakugo was behaving strangely today. She finished her shower and set aside her mixed feelings for later. Drying off, she inspected her body for more burns. The worst of it was on her arms, her shirt absorbing most of the rest. She pulled on the clothes, finding that they fit surprisingly well. After finishing that, she went downstairs to get some first aid materials from her bag and wrap up her arms. She had just finished that when there was a knock on the door. Without thinking, she answered the door. And immediately slammed it shut.

"Hey, that's rude!," a voice on the other side called out. There was another knock, and Senji braced herself. She slowly cracked the door open, confirming that there was definitely a familiar red-head standing just outside.

"He's upstairs!," Senji let Kirishima in and pushed him toward the stairs. He resisted, though, and shouted back at her.

"Senji?! Why're you here?"

"Hey, nerd! What's all that nois-"

Bakugo had come downstairs, shouting, after he heard the commotion. Once he reached the bottom step, he froze. Senji stopped trying to push her classmate, slumping forward in defeat.

"Oh! Hey, Bakugo! Come to the school pool, everyone's training there today," Kirishima changed pace fast enough to give the other two whiplash. Bakugo heavily protested the suggestion, and tried to get Kirishima to leave. Senji was still frozen in place, crushed by the awkward air of this situation.

"I know! I don't like being underhanded, but if you come with I won't tell anyone about you two."

"Huh?!"

The statement, and implications lurking in it, pulled Senji back from her internal struggle. She tried to stutter out an explanation but her voice was failing her. Bakugo, either irritated or too awkward from this exchange, agreed to go. Senji sighed and moved to pack up her things and head home. But the blonde grabbed the collar of her shirt and glared at her.

"You're coming, too," he growled.

"Huh? Why," Senji whined, but it was no use.
