"Castle, what are you doing?' Beckett asked the man holding a box behind his back, trying to look like nothing was out of the ordinary.
"What do you mean?" he innocently asked.
She just gave him a look, clearly not falling for it. "What's in the box?"
Castle sighed, knowing he had no choice but to tell her. He really didn't keep secrets very well. He handed her the box, watching her face to gauge her reaction.
Beckett opened the tiny box and gasped. "Oh, Castle."
"Kate Beckett, will you marry me?"
She nodded, love shining in her eyes. "Yes."
