Kurt looked at you like you had just told him the sky wasn't blue.

"Mein Spatzi," he said calmly, stroking your hair. "What do you mean? We've been dating for months. Everyone knows this."

You lived together. Shared a bed most nights. Cuddled on the couch. Spent all of your free time together.

He thought you'd both known you were dating this whole time. He's shocked to hear you just thought he was your close friend.
