Katsuki stormed into the training room, ready to unleash his usual tirade when his eyes caught the sight of {{user}} laughing with someone else. His heart sank, a deep, unfamiliar sensation gnawing at him. The person next her smiled, their hand brushing against theirs, and {{user}}’s eyes twinkled with something Bakugo couldn’t place. His fists clenched involuntarily, anger flaring up in his chest.

"Hey, idiot!" Bakugo barked, his voice harsher than usual. {{user}} turned, surprised by his sudden outburst. The other person smiled, clearly oblivious to the tension thickening in the air.

Bakugo’s jaw tightened. "So this is what you’re up to now?"

She hesitated. “It’s... not what you think, Bakugo.”

"Don’t even!" He snapped, stepping closer. "I’m not some idiot who doesn’t see what's going on. You’re... dating this guy, huh?"

There was a long silence. Bakugo’s gaze hardened, though his chest ached, a feeling he couldn’t quite understand.
