I'M NOT DEAD!!!!! I had half an hour before I had to leave for work and instead of doing anything productive, I finally finished this chapter. It'd been mostly done for weeks and I just had to wrap it up lolz. 

This chapter is triggering, just a warning. It appears I am unable to write a fic without SA trauma because I project or whateva. 

"Does Shoto know?" 

Izuku let out a harsh chuckle at the question. He raised one brow as he looked up at Bakugou like he was an idiot. "Why the hell would I ever tell Sho?"

A frustrated growl left the blond's lips as he pinched the bridge of his nose. After a moment, his red eyes snapped open, shooting daggers at his younger brother. "What the actual fuck were you thinking, Deku? How old were you? It better have happened recently or that fucker is dead, you hear me?" 

"Since when do you care?" Izuku snapped back, his arms crossing over his chest. He was still on the floor but now sitting crisscross with his back against the couch. 

"Is that really the question you're gonna ask right now?" Bakugou asked back in disbelief. "I just found out my freshly eighteen-year-old baby brother slept with someone six years older than him, and you wanna know why I care? Are you fucking shitting me right now?" 

Izuku's jaw clenched as he sat up straighter. "I don't know if you've noticed, but you haven't given a fuck about me for over a year." 

Bakugou took a minuscule step back as if physically struck by the words. "I am not the one who pushed you away," he seethed, his eyes narrowed, and pinned Izuku in place. 

"You're the one who left!" Izuku shouted, unable to help himself. "My mom died, and you packed up and went to college. You left me all alone, with no friends and no one to look out for me. Have you looked at me? I'm the goddamn poster boy for bullied kids. The second you and Sho left, I was thrown to the wolves. You didn't even visit! I didn't get texts, or phone calls, or anything. At least Shoto kept in touch. You disappeared." 

"That's a fucking lie! I texted you," Bakugou snarled back, taking a step into the living room. Kirishima's grip on his arm tightened as he silently watched the brothers fight. 

Another humorless laugh left Izuku's lips. "Oh, you're right. You texted me back a whopping five times. Yes, I did keep count, Kacchan." 

"Fine," the blond snapped. "I'm shit at texting, you know that, but I visit over the summers. You're the one who was always off getting fucked up at a party." 

"Do you think the drugs and sex are for fun, Kacchan? Do you think I enjoy being used and abused and fucked up out of my mind?" Izuku asked back, his nostrils flaring. "I do that shit because I have no other options! Sleeping with someone is a whole hell of a lot better than getting the shit beaten out of me, and being so high I can't think is better than being stuck alone with my thoughts. It's called coping, jackass, and maybe I wouldn't have to do it if you ever once put in effort." 

"Are you seriously going to blame all your goddamn issues on me?"

"Yes!" Izuku snarled, the word was spat from his mouth so hard and loud it made his throat burn. "Because I needed my big brother and you fucking left me." 

"I went to college!" Bakugou shouted back. Both men were beyond the point of caring about their volume, if they ever did in the first place. "You can't be pissed at me because I lived my fucking life, Deku. That's not fair." 

Izuku narrowed his eyes. "So did Shoto, and somehow he was still able to be there for me when I needed him. What the fuck happened to you?" 

Bakugou opened his mouth to retort but closed it before any noise left. He was at a loss for words, unsure of how to answer Izuku. 

Kirishima took a hesitant step forward, looking between the two men with unreserved caution. "Maybe you should-" 

"Stay the fuck out of it," Izuku snapped without realizing it. He liked Kirishima, he really did, but he was at the end of his rope. 

All the fire returned to Bakugou in an instant, his lips twisting back to his signature scowl. "Don't fucking talk to him like that." 

Izuku held his gaze for a second, then two, before scoffing and pushing himself to his feet. "Fucking typical. Take everyone's side but mine." 

"What the hell is that supposed to mean?" 

"Nothing," Izuku said, brushing himself off and waiting for his brother and Kirishima to get out of the doorway. He just wanted to leave. 

Bakugou's brows furrowed as he stared down at him. "I always took your fucking side. What the fuck are you talking about?" 

Well, if I'm already burning all my bridges, Izuku thought, holding Bakugou's stare. "Except for when it came to your friends." 

"What the hell are you talking about, Deku?" 

"Did you think Toji was the only one?" Izuku asked, taking a step closer to the blond. "You and Sho scared off any guy my own age, but never once stopped to think about your own friends. Do you know how hard it is for a five-foot fourteen-year-old to push off an eighteen-year-old linebacker?" 

"Okay," Kirishima cut in, stepping between the two men and placing a hand on Bakugou's chest as the blond visibly shook with anger. "This conversation, or fight, or whatever the fuck it is, is over. Midoriya, go upstairs with Kami and Sero, like, right now." 

Izuku reeled back at the order, his face pinched. "What? No." 

Kirishima threw a hard look over his shoulder, his eyes steely. "I wasn't asking." 

Izuku's eyes flipped from the redhead to his brother. Bakugou looked completely gone, his eyes unfocused and his fists clenching and unclenching at his sides. He'd known the blond his entire life and he wasn't sure he'd ever seen that look before. It was enough to make him reconsider Kirishima's command. "Fine," he mumbled, pushing past the redhead and slipping out of the living room. 

He'd just made it to the stairs when a roar and crash sounded from behind him, causing him to flinch and take the stairs two at a time. Practically sprinting, he flew into Sero's room like a bat out of hell. Unfortunately, in his panic, he'd forgotten that Kaminari had said they were in the blond's room. Sero's room was empty. 

As more crashes and yells sounded from the floor below, Izuku took a shuttering breath and scrambled to the bed, uncaring that it wasn't his own. He crawled in, burying himself under the blankets and curling up in a small ball as tears started to fall from his eyes. 

It wasn't like he enjoyed fighting with Bakugou. Sure, teasing the blond and pushing his buttons was fun, but genuinely fighting? Izuku hated fighting. What made it even worse was that he had admitted things he'd never said out loud before. He'd planned on taking his problems and trauma to the grave, but in a fit of anger, he'd spewed them right at his brother, Kirishima too. Now they knew and Izuku would never be able to get away from that. Every time they looked at him, he'd be reminded of it. No amount of showers or clean-cut lines across his arms could take that away. 

He heard shuffling out in the hall, but it didn't register in his mind. Muffled yells went unnoticed. It wasn't until the bedroom door softly clicked open that Izuku started paying attention. He pulled his legs tighter to his chest, tucking the blanket around him tighter in hopes that whoever it was would leave him alone. 

"Iz? Baby?" Sero's soft voice called, his footsteps muffled by the carpet as he took slow and careful steps toward the lump on his bed. 

Izuku didn't even realize that he'd started to relax at the sound of the other man's voice. His shaking had already started to die down and he carefully pulled the blanket down until his eyes could lock with Sero's. "I fucked up," he whispered, trying his damn hardest to not start sobbing again. 

Sero's face fell at his words, leaving him looking absolutely crushed. He hesitantly sat at the edge of his bed, worried he'd set Izuku off. 

It didn't matter, Izuku jumped into his arms without a second thought, holding onto him like a lifeline. 

"I didn't mean to tell him," he rushed out, tears already falling from his eyes yet again. "It just slipped out because I was so mad. I wanted to hurt him and I knew it would crush him to know, and it just- I just said it." 

Sero's arms twisted around him, holding him tight to his chest. "Calm down, baby. Take a few breaths. Everything's okay. Whatever Bakugou is freaking out about, he'll calm down soon and it'll be fine. This is just how he is, but he'll get over it," he cooed into Izuku's hair, trying his hardest to calm down the sobbing man. 

Izuku frantically shook his head, as well as he could while it was buried in Sero's chest. "He won't get over this. I just fucked everything up and now he's gonna go to prison for murder." 

Sero, who had been rubbing a hand up and down Izuku's back, stilled. "What're you talking about, Iz?" he asked softly. 

Loud stomping could be heard coming up the stairs, accompanied by yelling. Izuku tensed just as the bedroom door flew open. 

"Katsuki!" Kirishima hissed, grabbing onto his boyfriend's bicep in an attempt to pull him out of the room again. Kaminari trailed behind the two of them, looking unsure and frankly a little afraid.

"No, fuck this," Bakugou snapped, ripping his arm away. "Names, Deku. Right fucking now." 

"This isn't how we handle shit, Katsuki," Kirishima chided, his tone harsh and his eyes set in a glare at the blond. 

Bakugou whirled around, his nostrils flaring. "Someone put their fucking hands on my baby brother when he was fourteen and you're gonna tell me this isn't how we handle shit? Are you fucking kidding me?" 

"Kacchan!" Izuku shouted, his eyes wide and terrified as his brother spilled his darkest secret in front of Sero and Kaminari. 

"No. You know what? I'm just gonna call Shoto and we'll make a list of everyone we even talked to in high school and hunt them down." 

"You can't tell Sho," Izuku pleaded. "I wasn't even supposed to tell you, it just slipped out!" 

Bakugou opened his mouth, no doubt to yell some more, but Kirishima grabbed his wrist and sent him a hard look. "You're freaking him out even more and making it worse. You need to calm down," he said while holding eye contact until the blond finally took a deep breath and forced his shoulders to relax. 

"Fine," he growled out, looking like it physically pained him to say. 

"Wow, thanks for finally caring about my feelings in the matter," Izuku mumbled, only loud enough for Sero to hear. 

The raven-haired man lightly bumped his elbow into Izuku's arm, a soft scolding look on his face. "Let's not restart the fight, please," he whispered. 

"It shouldn't even be a fight!" Izuku exclaimed, throwing his hands in the air and taking a step back, away from everyone in the room. "It's my goddamn trauma; you guys have no say in it." 

"You're right," Kirishima agreed with a nod, looking at Izuku as if he were a cornered animal who would bite a moment's notice. Izuku strangely felt like he might. He really was Bakugou's little brother and apparently, there was no better Bakugou tamer than Eijirou Kirishima. "Which is why Kats and I are gonna go back to our room and not blab about this to anyone." His crimson eyes locked onto Bakugou's, narrowing as he spoke so the blond knew that he meant every word. "I know he's your baby brother and you just want to protect him, but it isn't your place to tell anyone or do anything without his permission. I know you know that." 

"Fuck all of you," Bakugou grumbled as he stomped out of Sero's room and down the hall. A moment later, his bedroom door slammed. 

Kirishima released a heavy sigh, pinching the bridge of his nose as he took a few breaths. Once he forced all the tension from his shoulders, he sent a strained smile to Izuku. "I'll keep an eye on him, but you really don't have to worry about him telling anyone. He's a hot head and abrasive, but he knows right from wrong. He won't do anything that'll hurt you." 

"I know that," Izuku snapped, not liking that some relative stranger was trying to mansplain his own brother to him. 

Kirishima nearly flinched at the harsh tone but caught himself. His smile slipped a little as he nodded, casting a quick look at his two friends before leaving the room to follow after his boyfriend. 

Once they were both gone, Izuku visibly deflated. The threat was gone and his fight or flight had officially shut off. He leaned back against the wall behind him, slipping down it until he landed on the floor. His head fell back until it met the wall with a soft thunk. "Fuck my life."
