The morning sun filtered through the curtains, casting a soft glow over Izuku's dorm room. The space was still, silent except for the slow, steady breathing of the two figures tangled together on the bed. Izuku Midoriya stirred first, his sapphire-blue eyes fluttering open, his mind still adjusting to consciousness. Warmth. His body was warmer than usual. Something soft was pressed against him, delicate fingers resting lightly on his chest. His normally sharp, analytical mind took a second longer than usual to process. Then, it clicked. His gaze shifted downward, where Nezuko Kamado lay curled against him, her bare form partially draped in his bedsheets, her soft pink eyes still closed in peaceful slumber. They were holding each other. The memories of the night before came rushing back—her flustered expressions, the soft hesitation that melted into acceptance, and the way their newfound connection had drawn them together. Izuku's mind, always methodical and precise, acknowledged a simple truth. They belonged to each other now. A soft sigh left Nezuko's lips as she began to stir, her lashes fluttering slightly before her pink eyes opened. It took a second for her sleepy gaze to adjust, but when she realized where she was, her entire body stiffened. Her face instantly turned red, and her grip on the sheets tightened. Izuku tilted his head slightly, watching her reaction with calm curiosity. Izuku {bluntly}: "You're awake." Nezuko's face somehow got redder. She quickly buried her flushed face into his chest, gripping onto him tighter, as if trying to hide from the reality of the situation. Her hands fumbled for her notebook, which was discarded on the floor along with their clothes from the night before. When she realized she couldn't reach it, she huffed silently and just began hitting his chest lightly—not out of anger, but pure embarrassment. Izuku let her, simply laying there, unfazed. Izuku {calmly}: "I assume you're flustered." Nezuko peeked up at him, her cheeks still hot, and gave him a look that screamed 'obviously'. He reached over, gently tucking a strand of hair behind her ear, his touch gentle but deliberate. Izuku {softly, watching her closely}: "Do you regret it?" Nezuko froze for a moment. Then, slowly, she shook her head. No. She didn't regret it. Even if the confession had been the fastest in history, even if it had all happened so suddenly, the reality was simple: She was his. And he was hers. Still, that didn't stop her from smacking his arm again, her face completely red. Izuku finally let out a small, amused chuckle, something rare for him. He gently pulled her closer, resting his chin atop her head, his arms wrapped around her in an uncharacteristically affectionate gesture. Izuku {murmuring}: "You're cute when you're embarrassed." Nezuko let out a silent whine, burying herself deeper into his chest. She was never going to live this down. Eventually, reality had to resume. The two reluctantly got up, getting dressed and regaining their composure—though Nezuko was still avoiding eye contact as she wrapped herself in her usual kimono, still flustered beyond belief. Meanwhile, Izuku had never looked more composed. By the time they left his dorm room, the hallways were already awake with the sound of their classmates getting ready for the day. As they stepped into the common area, all it took was one glance from their classmates—one single glance at Nezuko's still slightly pink face and the fact that she was leaving Izuku's room with him— And then— Mina {gasping dramatically, eyes sparkling}: "DID YOU TWO—?!" Nezuko immediately turned pink again, while Izuku, as always, remained completely deadpan. Izuku {calmly}: "Yes." Cue the absolute chaos. [Transition] Scene: Training the Fire Demon The U.A. Sports Festival was fast approaching, and Izuku Midoriya was making sure that Nezuko Kamado was more than prepared. Training together had become part of their daily routine, and Izuku took it seriously. Nezuko was strong, her Flame Blood Quirk made her a powerful combatant, but she lacked fine-tuned control and experience against high-level opponents. That's where Izuku came in. At the start of their training, Izuku had done something unexpected—he had given Nezuko a Quirk. It was a minor communication ability, allowing them to speak through thought rather than relying on her notebook. It was simple, efficient, and incredibly useful for their battles. Nezuko had been grateful beyond words. Nezuko {via thought, excited}: "Izuku! This is amazing! I don't have to write anymore!" Izuku {calmly, testing the connection}: "It will increase our efficiency. Now you won't have to stop mid-battle to communicate." Nezuko grinned, bouncing slightly in place. Nezuko {teasing}: "You're actually thoughtful, huh?" Izuku {bluntly}: "Obviously." Nezuko laughed softly, shaking her head. He really was something else. [Transition] Dressed in their U.A. gym uniforms, Izuku and Nezuko stood in the training field, facing each other. The sparring match was her request. She didn't want him to go easy on her—she knew his strength better than anyone, and she wanted to push herself. Izuku {calmly}: "You're certain?" Nezuko {nodding, determined}: "Yes! If you don't take me seriously, then what's the point?" Izuku watched her carefully, his eyes scanning her stance. Then, without any warning, he vanished. Nezuko's instincts kicked in immediately, and she flipped backward, dodging his incoming strike by mere inches. The air rippled from the sheer force of Izuku's movement. Nezuko {grinning, via thought}: "Fast, but not fast enough!" She spun and unleashed a burst of Flame Blood, her crimson fire slicing through the air toward him. Izuku barely tilted his head, dodging the attack with effortless precision. Izuku {casually, mid-dodge}: "Predictable." Nezuko gritted her teeth, pushing forward with renewed intensity. The fight was relentless. Each time Nezuko attacked, Izuku either dodged, countered, or redirected her strikes. But she was learning, adapting to his movements, getting faster and sharper with every exchange. Izuku noted her improvement. She wasn't just throwing attacks randomly anymore—she was calculating, predicting, reading his movements. Finally, she feinted left, then dashed right, getting in close and aiming a flaming kick straight at his ribs. For the first time, Izuku had to block. Her kick connected, heat radiating from her Flame Blood, and Izuku's arm trembled slightly from the force. She landed a hit. Nezuko grinned. Nezuko {teasing, via thought}: "Got you." Izuku glanced down at his arm, unimpressed. Then, without a word, he vanished again. Before she could even register his movement, he reappeared behind her and tapped her lightly on the back of the neck. Nezuko froze. She knew if that had been a real fight, he could have knocked her out instantly. She sighed in defeat, turning to face him. Nezuko {huffing, crossing her arms}: "Okay, fine. You win." Izuku watched her carefully, then spoke, his voice as neutral as ever. Izuku {calmly}: "You're improving." Nezuko blinked, surprised. Nezuko {softly, via thought}: "Really?" Izuku {nodding}: "Yes. You're adapting quickly. Your combat instincts are sharp. If you refine your movement and control, you'll be dangerous." Nezuko beamed, her earlier frustration disappearing instantly. She suddenly launched forward, wrapping her arms around him in a quick hug, her flames still flickering softly around her. Izuku stiffened slightly, not used to affection—but he didn't push her away. Nezuko {murmuring}: "Thanks, Izuku." Izuku {exhaling softly, placing a hand on her back}: "...Hn." The training was far from over, but she was getting stronger. And Izuku Midoriya would make sure of it.
