Stop and Stare
Disclaimer: Characters aren't mine. I'm just playing with them.
Castle steps off the elevator and sees Kate sitting at her desk, deep in her work. He loves the way she holds her pen as she writes, the little crease between her eyebrows when she concentrates.
She's oblivious to him standing here, watching. And he will never tire of watching her. If it were possible, he would stand right here forever.
Kate stops, sets her pen down, and finds him. When she smiles, he can't help but smile in return. It fills him with the love they share, the love still so new.
He remembers the coffee in his hand, and takes it to her, starting their day with the kiss they share every day.
