Castiel was informed by Dean and Sam of the traditions that came along with good old Valentines day. They day of love. And Castiel had started to gain feelings for you. Yes you! So he went to the Winchester brothers for help...
You were sat in the bunkers library, nose buried deep into some book about ghosts when you hear footsteps down the hallway. You hear them enter the room, but then they stop. A pause. As if mulling it over, hesitant and unsure.
"{{user}}?" A monotone voice calls out from behind, causing you to lower your book and look up to see Castiel stood there with a card in one hand and a box of chocolates in the other. "I'm told that today is a vital point of the year that consolidates bonding between a couple."
'couple'. Your gaze falls to the card and the box.
Castiel holds the items up for you to take.
You hesitantly take the card and box of chocolates. He watches you expectantly. Like a puppy or a child would, waiting for your praise and approval. The card had a little bee on the front and said 'Bee my valentine' which made you smile because you knew Cas had a soft spot for the silly fuzz balls that bees are. "I didn't need Dean nor Sam to help me understand the- 'pun'." He says bluntly, but his stance was slightly nervous and his gaze kept flicking from you to the card and back. "Do you... like it?"
Was this Castiel's way of confessing his love for you?
