One At A Time

*Kathryn Hahn*

#25: "You're Mine"

...

Y/n’s POV

I couldn't believe I was here, standing on the set of *Agatha All Along*, watching Kathryn transform effortlessly into Agatha Harkness. Seeing her in action always sent a thrill through me. She commanded the space, all wit and charm, and I was constantly in awe.

Today, though, Kathryn seemed off. Her energy felt different—sharper, more on edge. I thought it might be the long hours or the stress of nailing a complicated scene. But I quickly realized it wasn't work that had her in such a mood—it was *me*. More specifically, me chatting with Aubrey Plaza, who’d been charming, funny, and effortlessly captivating as usual.

“You must be Kathryn’s friend, Y/n?” Aubrey grinned, leaning casually against a wall. She had this playful look in her eye, like she was in on some private joke I hadn’t yet been clued into.

“Yeah, she invited me to the set. It’s incredible to watch her work,” I replied, keeping my tone light.

“She’s a force, that’s for sure,” Aubrey said, her smile widening. “You two seem...close.”

I felt a slight flush rise to my cheeks. Close didn’t even begin to cover it. Kathryn and I were something more than just “close,” but we kept things private, especially here where eyes were always on us.

“Yeah, she’s special,” I replied, trying not to give too much away.

Just then, I felt it—that intense, familiar gaze burning into me from across the set. I glanced over and saw Kathryn, her eyes locked on me. There was something darker in her expression, a tightness to her lips that I knew all too well.

Aubrey noticed too, following my gaze and smirking. “Well, I’ll leave you two alone. I wouldn’t want to get in the way.” She winked at me and sauntered off, clearly enjoying the tension she had stirred up.

I barely had time to process before Kathryn was beside me, her hand sliding around my waist with a possessive grip that sent shivers down my spine. She pulled me close, her voice low and edged with jealousy. “Having fun?”

My heart stuttered. I could feel her tension radiating off her in waves. “Kathryn, we were just talking.”

“Talking?” she murmured, her lips brushing against my ear, sending a tremor through me. “Looked like more than that.”

I swallowed, trying to stay composed under her intense stare. “Kathryn, it’s nothing. Aubrey’s just being Aubrey.”

But Kathryn wasn’t hearing it. Her grip on my waist tightened, her fingers pressing into my skin in a way that made my pulse quicken. “You think I didn’t see the way she was looking at you? And how you were laughing with her?”

Her voice was a low growl, and the heat of her jealousy was palpable. Normally, I might’ve tried to reassure her, but something about the way she was being so openly possessive had a strange effect on me—it wasn’t just intimidating, it was *exciting*.

“Kathryn,” I whispered, my breath catching as she turned me to face her fully, her hand now resting firmly on the back of my neck. “You’re being ridiculous.”

“Am I?” Her eyes darkened, and she leaned in closer, her lips hovering just inches from mine. “Maybe you need a reminder of who you belong to.”

The words sent a shiver down my spine, and I couldn’t stop the heat that pooled low in my belly. There was no mistaking the tone in her voice, or the hunger in her gaze. Kathryn was jealous, and when Kathryn got jealous, things always escalated in ways I could never predict.
