Lines We Cross

Lines We Cross

The next morning, Y/N woke to a series of loud knocks on her door. She groaned, rolling over in bed and burying her face in her pillow. 

“Y/N!” Bakugo’s voice rang out. “Get your ass up! We’re late for training!” 

Y/N sighed, dragging herself out of bed. After the events of the previous night, she wasn’t sure how to face him. Every word he’d said echoed in her mind—especially that final *pregnant* remark. It had been a joke, but the way his eyes had lingered on hers made it feel heavier than he probably intended. 

When she opened the door, Bakugo was leaning against the frame, arms crossed and his trademark scowl in place. He gave her a once-over and frowned. 

“Do you always look this shitty in the morning?” 

“Good morning to you too, Katsuki,” Y/N muttered, brushing past him to grab her training bag. “Thanks for your endless support.” 

“Tch. Let’s go,” he snapped, not waiting for her as he stormed down the hall. 

--- 

Training went as expected—intense, exhausting, and filled with Bakugo yelling at everyone, especially her. She could tell he was trying to push her harder, and while she appreciated his effort, his attitude was grating. 

“Move faster, Y/N!” Bakugo barked as she dodged his explosions. 

“I’m trying!” she shouted back, diving to the side to avoid another blast. 

“Try harder!” 

By the time training ended, she was drenched in sweat and ready to collapse. She shot Bakugo a glare as he approached, looking as smug as ever. 

“Why are you so mean to me?” she asked, half-joking, half-serious. 

“Because you’re too soft,” he replied, tossing her a water bottle. “If you can’t handle me, you can’t handle a real fight.” 

Y/N rolled her eyes but took a sip of water, too tired to argue. 

--- 

Later that evening, after showering and changing into more comfortable clothes, Y/N found herself back in the common room. She’d been hoping to unwind alone, but of course, Bakugo showed up not long after, his hair still damp from his shower. 

He plopped down beside her on the couch, grabbing the remote without asking and flipping through channels. 

“You know,” Y/N started, leaning back against the cushions, “you could’ve at least asked if I wanted to watch something.” 

“This is my TV time,” he replied, not even glancing at her. 

“Oh, is it?” she asked, her voice dripping with sarcasm. 

“Yeah.” 

The two of them fell into a surprisingly comfortable silence as some action movie played on the screen. Y/N glanced at Bakugo out of the corner of her eye, noting how relaxed he looked compared to his usual tense demeanor. 

“You’re quiet tonight,” she said softly. 

“Maybe I’m just tired of hearing your voice,” he shot back, though his tone lacked its usual edge. 

Y/N laughed, lightly punching his arm. “You’re such a jerk.” 

“Tch. And you love it,” he muttered, a small smirk tugging at his lips. 

Her cheeks flushed, and she quickly looked away. “You wish.” 

“Maybe,” he said, his voice quieter this time. 

She turned to look at him, surprised by the sudden softness in his tone. Bakugo’s eyes were fixed on the screen, but there was something in his expression—a vulnerability she rarely saw. 

“Katsuki?” she said, her voice barely above a whisper. 

He glanced at her, his crimson eyes locking with hers. For a moment, neither of them spoke, the air between them thick with tension. Slowly, Bakugo leaned closer, his gaze dropping to her lips. 

Y/N’s heart raced, her breath hitching as he closed the gap between them. But just as their faces were inches apart, Bakugo froze, his eyes narrowing. 

“Stop looking at me like that,” he muttered, pulling back abruptly. 

“Like what?” Y/N asked, her voice trembling slightly. 

“Like you’re daring me to do something stupid,” he replied, running a hand through his hair in frustration. 

Y/N’s lips curled into a small smile. “Maybe I am.” 

Bakugo groaned, leaning back against the couch and covering his face with one hand. “You’re gonna be the death of me, Y/N.” 

“Good,” she said with a laugh, her confidence returning. 

Though neither of them said it out loud, they both knew they’d wanted to do much more that night.
