A sense of possession is somewhat an alien concept to Castiel. Nevertheless, Castiel is proud of his first belonging - his surname.

It was the first thing he actually owned, except for the trench coat which was Jimmy's at first place. Now, he would go anywhere and people would call him "Mr. Winchester." Though it was unfamiliar at first, he had come to like his brand new surname, and preferred it to just 'Castiel'.

Soon, Castiel found himself owning so many thing. He had new clothes for an example. Dean's collection of wearable was so small they couldn't share & switch 365 days a year. After living in a domestic humanoid life for almost 2 months, Castiel finally had a T-shirt with no abbreviation nor a phase on. He had a pair of jeans, a suit, a jacket, a khaki pants, and even a polo shirt. In times, his own portion of closet grows, and they're back to sharing again.

Castiel had his private space in the house, it's just a small corner in their living room, but it was his, nonetheless. In that corner stood a hideous green with yellow polkadots sofa that Castiel had picked from IKEA. ("It goes with your eyes, Dean.") There's a small wooden end table near the sofa but you would notice a skyscraper of a book stack first when you entered the living area. The stack consisted of medical textbooks & journals, dessert recipes, fictions, and People magazines. Castiel would enjoy his tiny corner while Dean was paying attention to . Though he did not quite understand the presence of orange people in tabloid these days.

His most favorite possession was his song. Well, it was not his song, but it was his first time singing, and Dean later requested for the song as Castiel's song.

Castiel was sitting at the top ladder on their porch, admiring the sunset and the sound of birds going home when Dean came out. "Look what I've found in the basement." Dean grinned like a child, holding a dusted guitar. "She's a beauty." He sat down beside Castiel.

String after string, Dean picked her. A wider smile painted on his face."And she still knows how to rock."

"Her tone was off." Castiel noted.

"I just wait." Dean licked his lips, pulling each string, adjusting each one. By the time he played a chord for a fifth time, the guitar sounded like a harp to Castiel.

"Very good, Dean." Castiel nodded in approval, he knew Dean was intelligent and versatile for a human, though Dean didn't give himself much credit. Dean winked and started playing.

The eight-notes intro gave Castiel a warm feeling inside, like he found his home and his paradise again. Castiel looked at Dean whose face glowed in the last light of the sun, and he knew he wasn't wrong. He even knew this song from Dean's casette. So, when Dean glanced at him as a sign for the verse, Castiel sang.

"She's got a smile that it seem to me… remind me of my childhood memory where everything as fresh as the bright blue sky..yy"

Playing a guitar, Dean looked like a proud lover, and he was. He skipped the next verse and went "Who sweet child of mine."

They made an eye contact but both were too shy to let it linger too long. They almost chanted together "Who sweet love of mineee." It was Castiel who trailed off that high note. Dean shook his head as he found it horrible and adorable at the same time. Dean put down a guitar, but didn't stop singing.

"He's got an eye of the bluest sky as if they thought of rain. I'd hate to look into those eye and see an ounce of pain…"

"You changed the lyric."
"But it makes sense to me."

Dean leant in closer, pressing his lips on Castiel's, breathed in the angel's scent.

And that, was how Castiel got his song.
