#from that day on kazui vows to never make mahiru upset under any circumstance 👍

[good-beanswrites]

I remember seeing a fanart on Twitter of Mahiru and Shidou jumping Kazui after they found out his crime. Can you do a fic of them beating his ass after finding out his crime

RIP Kazui sdfasdf -- thank you for the request pal!! (I assume you mean the cheating theory and not homophobic 06 09 LMAO) Mikoto is always down to stir things up, though it took a while to picture what Mahiru would be driven to. In the name of love I think she'd become a force to be reckoned with 👏👏👏 I hope you enjoy >:3

Some occupants of Milgram are excellent at lying. They hide a great many things, and pull a great many poker faces. Other occupants are the very worst at it. They wear their heart on their sleeve, for better or worse. Kazui was one of the excellent ones. Mahiru was not. 

When Muu asked if he understood any of the celebrity news they were discussing at dinner, he convinced her that he knew everyone they’d mentioned with a grin. When Mahiru told Fuuta his hair looked “perfectly stylish” after he tried cutting it himself, she got a much rougher reception as he saw right through her.

When Es declared Kazui forgiven “despite his infidelity,” he had maintained the perfect expression to hide the fact that they were a bit off. When Mahiru waved her fingers and told Kazui nothing was wrong, he could plainly see there was bitterness underneath her words. 

He couldn't fathom what he'd done to upset her – they'd had pleasant conversations during meals, and played games in the common area. The pair never spoke about it, though; there was no need to make her any more angry. Kazui had nearly forgotten about it by the time Es disappeared. 

Mikoto proved a slightly better liar, but Kazui caught some odd expressions from him as well. They were smoking in silence together when there was a knock at the door. He answered with his cigarette still resting between his teeth. He was surprised to find Mahiru glaring up at him.

She drew herself up, appearing taller and more intimidating than usual. There was a fire in her eyes he hadn’t experienced before. “In the name of true love –!” she cried. She squeezed her eyes shut and wound her arm back. Kazui looked at her quizzically. It wasn’t as if she was going to slap anyone. 

She slapped him. Hard.

The force knocked the cigarette from his lips and sent him coughing on the smoke. Suddenly Mikoto was behind him, holding his arms in place. 

“Woo! He’s all yours, Mappi!”

Seeing the sudden turn of events, Shidou leapt in to help. He tried to wrench Kazui away by his right arm, but Mikoto held fast to his left. He didn't particularly enjoy being the subject of their tug-of-rope. His legs stumbled between them, falling a bit to one knee. He was left sputtering for breath, pinned between them and facing a fierce Mahiru. He didn't know when she and Mikoto planned all this, and his mind was spinning too fast to think too hard on it.

Kazui looked frantically to her, but her rage was rapidly dulling. She slowly returned to looking exactly 154 cm short. Her mouth twisted into a wobbly frown. “W-what do I do?”

“Eh? You said you wanted to teach him a lesson! Let's go, throw some punches! A few kicks!” 

She covered his face with her hands. “I've never hit anyone before!”

“But, you just did?” Mikoto adjusted his hold. 

“Not like that!”

Shidou bristled. “Why is she hitting anyone?”

Reminded of her reasons, Mahiru uncovered her face. “Kazui Mukuhara – this is what you get! This is what you get for being a dirty, rotten, cheater!” She tried again, bringing her arm back. The movement seemed to pain her more than anything.

He was met with another stinging slap, despite Shidou’s protests. Kazui gasped for air, finally catching his breath now that the smoke had cleared from his lungs. His hair had fallen in front of his eyes.

“We know what you did,” Mahiru said. “Oh, we know everything.”

Mikoto made a sound of agreement from behind. “It’s pretty fucked up, comforting Shidou about loosing his wife like that, while you’re a cheater yourself.”

Kazui opened his mouth, but Mahiru interrupted.

“I don’t want to hear any excuses! Es may have forgiven you, but in the name of true love, I’m going to punish you all the same!”

Although Mikoto was stronger than Kazui had given him credit for, he didn't have the muscle to completely hold him. Kazui pulled himself from the grip, grabbing Mahiru’s wrist as she swung for him again. Shidou took a step back, as the situation fell under control.

Kazui smiled gently. “You don’t need to punish anybody. Es didn’t get the full story.” He released her.

“Oh yeah?” came her incredulous reply. She lifted her fists as if preparing for a brawl, but she had one of the worst forms he'd ever seen. She bounced on the balls of her feet, brandishing her fists. She looked like she was going to start crying.

“Mahiru, I didn’t cheat on my wife.”

“Oh thank god.” She dropped her fists. 

Mikoto raised an eyebrow, either from the turn of events, or he was annoyed at how effortlessly Kazui had escaped him. “There was no other woman?”

He let out a deep laugh. “Not at all.”

“Oh, I just knew it!” Mahiru leapt forward to hug him. 

“If you knew it, why did you slap me…?”

“I’m sorry! I hope it didn’t hurt! Oh, and I was going to try and hit you again… I’m so sorry!” 

She pulled back from the embrace, looking to him with horror. He continued with his warm expression.

“No, no. I was just surprised. I wasn’t afraid of another hit.”

She turned to Mikoto and Shidou to express her excitement, and Kazui reached up to rub his burning cheek. His eyes flicked to Mahiru with uncertainty. He was, after all, an excellent liar.
