Last chapter ya'll. I hope you've enjoyed the story! :D

Beckett sits tiredly in her chair, despite the good night's rest she had before. Her eyes close, and her neck bends backwards.

"Kate?"

Her neck snaps forward.

"Yeah?"

"Uh…" Castle pauses awkwardly, formulating a reply.

"Well," he begins, "I had some extra time, and so I got this for you." He holds out a velvet box, much like that of a wedding ring box.

"You're not going to propose to me, are you?" Beckett asks, raising an eyebrow in taunt.

"Well…actually," stutters Castle.

Beckett's eyes widen.

Castle prepares to bend down on one knee, but abruptly stands. He quickly opens the box.

"Just kidding," he says, a boyish grin appearing on his face.

Beckett glares, and peeks at the velvet box's contents for the first time.

It's a thin, gold necklace with a small gold pen charm hanging from the bottom.

"It's beautiful. But Castle, I can-" Not letting Beckett finish her sentence, he lifts the necklace from the box, and places it around her neck. His warm hands feel good on her cold skin.

"Like I said," he continues, bending forward so that his lips are near her ear.

"You don't know how I work."
