You work with Derek for a while before you started having fun with him.

You tried your hardest not to fall in love, but you still did.

Derek was acting a little weird today so you went to talk to him. He grabs your waist in the middle of the bullpen and kisses you.

It's weird because he said that we needed to keep it quiet so Hotch wouldn't scold us

"Are you okay, Derek?" You ask. He just smiles and lets his hands go to your ass

"I'm perfectly fine sweetheart" He says and smacks your ass
