High on Sparks || KAMIBAKU

the spark

The festival had finally died down, leaving only the soft hum of the cleanup crew working through the night. Most of the students had already gone home, the excitement of the day now fading into tiredness. But Denki, still buzzing from his performance, couldn't quite shake the adrenaline coursing through him. He sat backstage in the corner, strumming his guitar absentmindedly, the melody soft and introspective.

His bandmates had already left, Sero giving him a final thumbs-up, Uraraka teasing him about his "secret admirer" in the crowd, and Momo smiling warmly before they disappeared into the night. Denki hadn't been able to stop thinking about the way he had sung that song—how every note had felt like he was opening up a little more of himself. He hadn't expected much of a reaction from Katsuki, but part of him still held out hope.

He hadn't noticed when Katsuki appeared, standing just outside the dimly lit backstage area, watching him in silence. Denki was lost in his thoughts, fingers lightly brushing against the strings, until a sharp voice cut through the quiet.

"Oi, idiot."

Denki jumped, his fingers slipping on the guitar strings. He looked up, his heart skipping a beat when he saw Katsuki standing there, eyes narrowed in frustration.

"Bakugo?" Denki's voice was quiet, uncertain. He hadn't expected to see him back here after the performance. "What's up?"

"Cut the crap," Katsuki snapped, walking towards him. "Was that song about me?" His tone was demanding, almost angry, but there was an underlying confusion in his voice. It was as if he couldn't quite figure out why he was feeling this way—why that damn song was messing with his head so much.

Denki froze. His mouth went dry, and his heart pounded in his chest. He had known this moment was coming, but now that it was here, it felt overwhelming. He set the guitar down beside him and looked at Katsuki. For once, he wasn't smiling, wasn't trying to hide behind his usual carefree demeanor. He was serious, vulnerable in a way he rarely showed anyone.

"Yeah," Denki admitted softly, his voice barely above a whisper. "It's about you."

Katsuki stood there, staring at him for a long moment, the tension between them thick and palpable. Denki could feel the weight of Katsuki's gaze on him, the frustration and confusion mixing with something else—something that made Denki's heart race even faster.

"Why didn't you just fucking tell me?" Katsuki finally growled, the irritation in his voice obvious now. "Why the hell did you have to make it so complicated?"

"I—I don't know," Denki stammered, running a hand through his messy hair. "I guess I was scared. I didn't know if you'd... if you'd feel the same way. I didn't want to ruin our friendship or make things weird between us."

Katsuki let out a sharp breath, and for a moment, Denki wasn't sure if he was angry or just trying to make sense of everything. Katsuki opened his mouth to say something, but then, without warning, he stepped forward and grabbed Denki by the collar of his shirt. Denki's breath caught in his throat as Katsuki pulled him closer, their faces just inches apart.

"Don't fucking make me guess anymore," Katsuki growled, his voice rough. "If you feel like this about me, then I want you to show me. Don't hide it behind stupid songs."

Before Denki could react, before he could even process the words, Katsuki pressed his lips against his in a sudden, heated kiss.

It was electric.

The moment their lips met, it felt like a spark had ignited between them. Denki's entire body went numb, the world around him fading into nothing as the kiss deepened, their mouths moving together urgently. It wasn't gentle, it wasn't careful—it was a rush of emotions, of things unsaid, of months of tension building up between them. Denki's hands instinctively cupped Katsuki's face, pulling him closer, while Katsuki's grip tightened on his collar, pulling him into the kiss like he couldn't get close enough.

Denki could feel his heart pounding in his chest, could feel the way his body responded to the kiss—warmth flooding through him, the sensation of Katsuki's lips on his sending a thousand volts of energy straight to his core. It was everything Denki had ever imagined, but more intense than anything he had expected.

Then, just as suddenly as it had started, they pulled apart, both of them gasping for breath. Denki's lips tingled, his chest rising and falling rapidly as he tried to regain some semblance of control.

They were both red—Katsuki's face flushed with heat, his chest heaving as if he couldn't catch his breath. Denki, on the other hand, couldn't stop the nervous smile that tugged at his lips, his hands fidgeting as he looked down at them. Neither of them said anything at first. The silence between them was thick, filled with the weight of what had just happened.

Denki couldn't help but laugh nervously, rubbing the back of his neck. "Well... that was... wow."

Katsuki, clearly flustered but trying not to show it, looked away, his cheeks still bright red. "Tch, don't say it like that, idiot," he muttered under his breath, but the tone in his voice was softer than usual.

Denki took a step back, still processing what had just happened, but before he could say anything, Katsuki reached out and gently placed his hand on Denki's cheek. The touch was tender, not like the usual forceful gestures Katsuki was known for, and it made Denki's heart skip a beat.

"Look at me," Katsuki said quietly, his voice rough but sincere.

Denki met his gaze, and before he could even react, Katsuki leaned in again, this time pulling him into a kiss that was even more heated, more urgent than the first. This kiss wasn't soft, wasn't tentative—it was filled with all the frustration, all the confusion, all the feelings that had been building up for months. Denki's hands roamed up to Katsuki's chest, feeling the solid muscle beneath his fingertips, and then up to his shoulders and neck, pulling him closer as their lips moved together in a frenzy.

Katsuki's hands were no longer gentle. They slid around Denki's waist, gripping him tightly, and then he pushed him back until Denki's back hit the wall behind him. Denki's breath hitched, his hands still roaming, now desperately clutching at Katsuki's shoulders as the kiss deepened, growing more intense. His body pressed against Katsuki's, their hips aligning as they both stumbled slightly, their movements clumsy but full of passion.

Denki's mind was racing, but he couldn't stop himself. Every part of him wanted this, wanted him—wanted Katsuki.

And then, just as quickly as it had started, they both froze.

There, standing at the edge of the hallway, were Sero, Uraraka, and Momo. They hadn't said a word, but the amused looks on their faces were unmistakable.

"Well, this is a sight," Sero said, his voice low and teasing, though he didn't step forward.

Momo smiled softly, her eyes gleaming with understanding. "We should probably... leave them alone for a bit," she whispered, gently tugging on Uraraka's arm.

Uraraka, looking almost too flustered to speak, nodded vigorously. "Uh-huh, right, let's go!"

The three of them slipped away quietly, leaving Denki and Katsuki alone again. Denki felt a rush of embarrassment, his face burning even more than before. He quickly looked away from Katsuki, trying to gather his thoughts.

Katsuki, on the other hand, didn't seem to care. He just grunted, a small smirk playing at the corners of his lips. "Tch. Whatever. Let them see," he muttered, before turning his attention back to Denki.

Denki chuckled nervously, but then he met Katsuki's gaze again. This time, it felt different. No more confusion. No more hesitation.

This time, it felt real.

"Hey," Denki said softly, still smiling despite the flush on his face, "I guess that wasn't too bad, huh?"

Katsuki raised an eyebrow, but there was a softness to his gaze now, something that hadn't been there before. "Tch. You're such an idiot."

But his voice lacked the usual venom. It was something else—something that made Denki's heart swell in his chest.

"Yeah," Denki grinned. "But I think you like it."
