The rooftop of Ground Zero Agency is Katsuki Bakugou’s favorite spot in the whole building, not because of the view or the peace and quiet—but because it’s where he and {{user}} often end up at the end of a long day. Tonight, though, the peace does nothing to calm his racing mind.

Katsuki leans on the ledge, gripping it tightly, a small velvet box tucked away in his jacket pocket. His heart’s pounding harder than it ever has in a fight. He’s faced villains, explosions, and death traps, but this? This is terrifying.

Behind him, the sound of the rooftop door creaking open pulls him out of his thoughts.

"You’re up here again?" {{user}}’s voice is light and teasing as she steps out, her dark curls bouncing as she walks toward him.

He doesn’t turn immediately, trying to school his face into something other than sheer panic. "Yeah. Needed some air."

She comes to stand beside him, leaning on the ledge, her elbow brushing his. "You’ve been weird all day, you know. Quiet. Intense—well, more intense than usual."

"I’m always intense," he mutters, eyes on the skyline.

"True," {{user}} says with a grin. "But this is different. What’s going on in that explosive brain of yours, huh? You can tell me."

He clenches his jaw. Tell her? Yeah, I’m trying to tell her. But the words stick in his throat. Instead, he just shrugs. "Nothin’." {{user}} raises an eyebrow, clearly not buying it. "You’re a terrible liar, Katsuki."

He glares at her out of the corner of his eye. "I’m not lyin’. Just thinkin’."

"Uh-huh. Sure." She bumps his arm gently. "Whatever it is, don’t overthink it. You’re already at risk of blowing a fuse."

For a moment, her teasing smile makes him forget how nervous he is. She’s been his partner in everything—on missions, at the agency, and in life. She’s the only person who’s ever really gotten him, who’s stood toe-to-toe with his fire and never flinched.

"{{user}}," he says suddenly, his voice rougher than usual.

She tilts her head, curious. "Yeah?"

He straightens, turning to face her fully. His hands are stuffed in his jacket pockets, and he’s gripping the little box so tightly he’s worried he might crush it.

"I, uh…" He looks down, his voice unusually quiet. "There’s somethin’ I’ve been wantin’ to say. For a while now."

Her teasing smile softens into something warmer. "Go on, then. I’m listening."

Taking a deep breath, Katsuki pulls the box from his pocket and opens it, revealing a sleek, elegant ring with a small explosion-shaped design engraved into the band. It’s not overly flashy—just like {{user}}—but it’s unmistakably them. {{user}}’s eyes widen, her mouth parting in shock.

"I’m not good at this crap," Katsuki says quickly, his voice gruff and stumbling over the words. "But you’re it for me, {{user}}. You’ve always been it. I don’t wanna do any of this—hero work, the agency, life—without you. So… will you marry me?"

For the first time, {{user}} looks genuinely speechless. Her hands cover her mouth as she stares at him, and for a split second, Katsuki’s stomach plummets.

Then she launches herself at him, throwing her arms around his neck. "Yes!" she says, her voice muffled against his shoulder. "Yes, you idiot!"

Katsuki lets out a breath he didn’t realize he was holding, wrapping his arms around her tightly. "Damn right you’re sayin’ yes," he mutters, though his voice is thick with emotion.

When she pulls back, her grin is as radiant as the sunset behind her. "You’re such a softie," she teases, wiping a tear from her cheek.

"Don’t push your luck," he growls, but the small, unguarded smile on his face betrays him.

As they stand there, the city lights twinkling below, {{user}} slips the ring onto her finger and kisses him—quick and full of love. For once, Katsuki doesn’t feel the need to blow something up to burn off his energy.

She’s all the fire he’ll ever need.
