It was Valentine's Day and you were a little giddy. You had found one of those cheesy cards that you use to pass out in grade school. It had a bee on it and it said "I'm buzzzzy for you!". You planned to give it to Castiel. You had always had a crush on the adorable angel, and hopefully, today would be a good one and he would return the feeling.
When you heard the flutter of wings you smiled.
"Hello Y/N," he greeted, "where are the boys?".
"Sam went to get some food," you answered, "and Dean is probably at the bar trying too smooth talk him a valentines date," you made finger quotes at the word date.
"Yes, this holiday can be over exciting," the angel said sitting in the chair next to you.
"Have you ever gotten a valentine?" you asked making sure to grab the one you had under a book before he saw.
"No, I've haven't had the pleasure of a valentine," he said.
"I have a gift for you Cas," you said handing him the card. He read it and made that all to adorable confused face.
"What is this?" he said.
"It's a valentine's day card," you explained, "what do you think?" The angel suddenly smiled and reached into his pocket.
"I think great minds do think alike," he said handing you the same kind of card only it had a bee on it holding a heart that said "Bumblebee mine," on it.
"Are you trying to ask me to be your girlfriend Cas?" you asked hopeful.
"Yes Y/N," he said, "you're very sweet, loving, and your soul is just as beautiful as you are,". You blushed as you leaned over and kissed his cheek.
