It started subtly. One moment, Sienna Shaw was strapping on her signature armor, the sleek metal plates glinting under the dim lights of the safehouse. The next, a faint hum echoed through the room—soft, almost musical, but unmistakably emanating from her armor.

“You… do you hear that?” Sienna asked, her brow furrowed as she glanced at you.

You froze. “Hear what?”

“The resonance,” she whispered. Slowly, she took a cautious step toward you. “It’s… reacting to you.”

Your heart skipped. “Reacting… how?”

Her eyes narrowed, intense and searching. When you raised your hand slightly, a faint pulse of light rippled across the armor’s surface, tracing the contours like electricity dancing along metal. Sienna’s breath hitched, and a half-smile—equal parts awe and disbelief—crossed her face.

“You… you’re like me,” she murmured, voice low. “I’ve never felt this before with anyone.”

The hum grew stronger, surrounding the two of you like an invisible tether, as if the armor recognized something in you, something shared. You reached out instinctively, and when your fingers brushed the cold metal, a shock ran through both of you—not painful, but electrifying, intimate.

Sienna’s gaze locked on yours. “This… this changes everything.”
