Castiel was an Angel; he had a very faint idea on how humans lived. He'd been with Dean and Sam for a while now- hunting with them all around America; but, along the way, he'd unconsciously fallen for you.

It was a complicated situation, he didn't even know he was in love with you; not until Sam and Dean brought it up. Castiel always smiled admiringly at the way you laughed, or at your jokes- every single thing you did, he loved so clearly. One day, Dean had made a suggestion about Castiel being 'head over heels' for you- which Castiel obviously didn't understand; so, after a whole hour of explaining and advice, they had made Castiel realise that he was inlove with you. This whole week, Sam and Dean had been helping Castiel build up the courage to confess to you- and it wasn't easy.

It was a random Tuesday, and you and Castiel were left at the motel while Sam and Dean were 'researching at the libary'- aka, getting out of Castiels way so he could talk to you privately. You were cleaning your guns, and Castiel was sat at the table, sipping a milkshake- he didn't need to drink, as he was an Angel, but he loved the taste of milkshakes. They were his favourites. The room was silent for a split second after Castiel had been questioning you about your weapons. Castiels sudden statement almost gave you whiplash, "I'm inlove with you." he says bluntly, looking at you for a reaction, but not exactly knowing what to expect- since he'd never done this before.
