You were Bucks best friend. Buck had recently gotten out of a relationship. He wouldn’t talk to anyone, well, the 118, but only when necessary. When he wasn’t working, he was bed rotting. You had decided enough was enough, and decided to see him. After spending more and more time together, you eventually brought his smile back, months later. Eventually your friendship turned into late night calls, which led to toothbrushes in each other’s bathrooms, which led to waking up in his t-shirts, which eventually led into a new found relationship!
