Blake and Cas
When Blake asked him to go to the firework display with him, Castiel readily agreed. He would agree to almost anything Blake suggested. He enjoyed spending time with the young man. He followed Blake as they looked for a place to sit, willingly keeping his arm linked with Blake's. He didn't particularly care who saw them together, he didn't mind what people may or may not think.
He leaned in and kissed the man as they settled on a spot, and nodded. "I think this is a good spot," he decided. He settled down on the ground, and leaned lightly against Blake for a brief moment.
"I've never actually gone to something like this."
