PROMPT: Yin and Yang/Opposites

They were opposites.

That guy; he's got an ego higher than anyone else's.

He's noisy. He's selfish. He's always angry.

Her, on the other hand — she's humble. She's not very loud mouthed, and is considerably selfless at times. She's rarely mad.

That's what she thought at first. Who would've known that deep inside, even if it's just a little bit, they would get along, have a talk, and perhaps be friends?

In her eyes, Bakugou Katsuki may have been a rash-acting idiot, but he was much more than that. He actually knew how to apologize, to stay calm and silent — that was indeed surprising.

It was 2AM, a week after the incident on a Saturday night.

"I keep wondering why the fuck you did that." she recalls his cracking voice that day, echoing in the empty common room. It surprised her. She's heard from Kirishima that he had been quiet ever since he was escorted back to the dormitories just after getting interrogated. Yaoyorozu tenses up. The humble girl that she is, she denied. "I didn't do anything, Bakugou-san."

Bakugou gives her an eyeroll, "I already knew everything when the police interrogated me, don't be cheeky enough to lie, Ponytail!"

Bakugou sighs loudly, plopping down in the couch in front of her aggressively.

She looks down, embarrassed for some reason. "I — I see. Uhm, h-how did it go?"

"Was fine." he snorts, but it was evident that he was thinking of something deeply. He was gentle, vulnerable it even seemed. "What about you?" The blond asks while pointing directly to her head.

Startled, she replied immediately. "I'm okay!" she raises both her hands up in defense. "If I was careful enough, I would've been able to avoid that. It was my fault."

"…Thanks." he mumbles.

"I keep wondering why you did that even though we ain't anything. Deku was expected to do that. He's a fucking idiot, and Icy Hot? That bastard would follow him wherever. Kirishima's a friend but I don't know why on Earth you, of all people, would help."

If it wasn't just the two of them in the common room, it would've been inaudible.

Yaoyorozu couldn't help but smile. "Well isn't it because it's my responsibility?" as the vice class rep? She looks at him, much relaxed than she was earlier — "I really wanted to help."

He looks away, slightly distracted for a second because of her smile. "Weirdo."

A second later, he sees her stand up from his peripheral view. "Hold up."

She turns around, looking at him straight on the eyes. "Yes?"

"You didn't save me, got that? You ain't do shit!" Bakugou scratches his hair a little bit, his brows slightly furrowed while doing so. "I'll—"

"You're welcome, Bakugou." she giggles before turning back, "Goodnight." When she left, the boy sighed in defeat. "That bitch saw through me."

It makes her happy. You could say that sometimes, the two would meet each other at the common room — the same time, same day of the week, and just appreciate each other's company.

Bakugou wonders how they got along in the first place. They were opposites, after all.
