- 6: And paint it over -

He couldn't have gotten out of that classroom any faster. He's gripping his backpack strap like it's the one making him pissed off. He doesn't know where he's going or how he's going to find Deku, but that doesn't matter right now. What matters is the searing anger in his chest and the prickling feeling every time he thinks about that asshole and Deku being alone together. People are getting out of their classrooms, the hallway soon filling with noise.

There is no sign of the two on their normal spot, and Katsuki searches elsewhere, the locker rooms, the gym, even the library. With every passing moment he's only getting more and more pissed off. Most people have left the school to go home, only some staying back for extra activities or studying. But he isn't going to give up. Once he catches that bastard, he's going to make fucking sure- 

"W-Wait, hold on-!" 

He hears talking in the bathroom and stops right in the hallway. Their school has bathrooms where the doors can lock from the inside, and Katsuki is a hundred percent sure he just heard Deku's fucking voice behind that door. Now that the hallways are quiet, the people inside aren't that hard to recognize. It definitely is Deku, and... 

"Okay, okay, sorry... I'm just excited, I'll go slower." 

That fucking extra. 

Blood hammers in his ears, every part of his body screaming to get over there, to rip the two away from each other, because he has a pretty good fucking idea of what they're doing in there. Katsuki stares at the door, his anger building up more and more. He's going to kill that fucking piece of shit and make Deku watch, he's going to make sure this shit doesn't happen again. He doesn't want to ask why he feels like this. 

He doesn't question it, or even fight, as slams on the door over and over. He doesn't say anything, not yet. He hears Deku let out a small yelp, and the extra hushing him softly, then the door opens. Katsuki lands on Deku first. His hair is an even worse mess then before, his lips red and his face flushed. A fucking look he recognizes. The only thing that's new are all of the marks up and down his neck, his disheveled uniform letting him look at them all clearly. 

He then looks at the bastard, who is looking at him with surprise. 

"Baku-?" 

He punches him right in the fucking face. His fist connects with his jaw and his head crashes against the tiled bathroom floor. Deku yells, trying to go over and help him, but he grabs Deku by his wrist and begins to drag him away. He fights, pulling back hard, yelling at him and digging his own nails into his hands. It only makes him tighten his grip. His whole body feels like it's one more second from blowing up, and he really doesn't have the patience to put up with Deku's bullshit anymore. 

He feels his nails digging into his skin, only gripping tighter. He won't let him get away this time, he won't let him run away with that nobody. He doesn't get very far, still a couple feet away from the usual spot before he finally lets him go harshly, ripping some skin from his wrist and under his fingernails. Deku lets out a hiss of pain, gripping his wrist with his other hand, not even getting a word in before Katsuki speaks. 

"Deku. If I see you with that piece of shit ever again, I'm going to kill the both of you. Do you fucking understand?"

He seethes it out between his teeth, with the intention of burning every single word into Deku's fucking brain so that he knows how serious Katsuki is about this. He eyes the marks on his neck, disgusting, repulsive marks that make Katsuki's anger light up even stronger. Deku looks at him, his eyes glinting in anger and pain. No matter how cold his voice is, or how much he looks like he wants to punch Katsuki in the face, he can still hear the little crybaby holding back tears.

"You just punched him! He could be seriously hurt and-!"

"Who fucking cares about that?!"

Katsuki shoves his shoulder, making sure he can hear the sound it makes when it hits the brick wall, digging the palm of his hand into him for good measure. Deku winces, shutting his eyes tight for a moment before opening them slowly to glare at him. Katsuki fills with the urge to wipe it off his fucking face. 

"Do you honestly think I give a shit about that useless bastard?! What the hell did you think you were doing in that locked bathroom hah?! What made you think you could-!?"

The tears in his eyes build up, but he still holds them in. Deku sniffs loudly, his voice watery as he yells back. He still looks pissed, and the expression makes Katsuki's own anger build up. 

"How come you just get to do whatever you want, and I can't?! How come whatever we are isn't a relationship to you, but you think you can control what I do with other people?!"

Katsuki opens his mouth to respond. It wouldn't have been the best response, probably just yelling at him to shut up littered with a thousand insults, and including the fact that he isn't the one going around making out with people. But Deku still continues, his voice quieter. 

"Just because you don't know what you want from me doesn't mean I'm just going to wait around for you to figure it out." 

Deku rips his hand from his shoulder and bolts off, his backpack hanging on one strap as he runs off. Katsuki is about to go after him, tackle him to the ground because who the hell does he think running off when Katsuki isn't finished with him yet?! But he doesn't, his feet stay planted on the ground as he watches him rush off back into the school.
