Although they hadn't said anything explicitly yet, both Cas and Dean had silently agreed that being boyfriends was clearly the best option. Of course, Cas's dad coming home and catching them a few minutes after they had started kissing shook Cas up considerably. But his father just gave them a small smile and said, "Dinner in five boys, if you're hungry," before leaving the door open behind him as he left. Despite being grateful for his father's acceptance, Cas couldn't stop freaking out until Dean had kissed him senseless again, which was proving to be a surprisingly easy thing to do. Dean declined staying for dinner though, saying Sam would probably be dying for an update. He was proved right when he got home to find Sam sitting in their living room and reading a book while impatiently tapping his foot.

"So?" he asked Dean as soon as his older brother set foot in the room. Dean just smiled and raised his eyebrows suggestively. This successfully got an eye-roll out of Sam, but he didn't do a very good job hiding his happy, and slightly proud, smile. "Mission accomplished," he thought proudly to himself.

The next day, Jo just smiled at them when Cas grabbed Dean's hand on the way out of school. After they had left the English classroom, Cas reached out his other arm to link with hers. Jo let out a small, happy laugh as she grabbed Cas's arm, and the three of them walked out of the school together. Even though things were clearly different now, all of them couldn't help thinking it felt like everything was finally back to normal.

Months passed. Dean and Cas eventually cleared up all of the confusion surrounding the way they had gotten together, and were both amazed at how slow they had been to understand the other. Jo was just amazed that Cas had mistaken Dean's "inferior" kissing for her own, which earned her a laugh from Cas and an impressive glare from Dean.

The end of their senior year was approaching quickly, and while Jo and Cas were excited, Dean found himself dreading it. Jo was going to Chicago State University and Cas had gotten accepted into Northwestern. They were both thrilled that they were going to be so close to each other, even if they weren't going to the same school, but all Dean could think about was how they would be leaving him behind. It wasn't like he regretted choosing not to go to college. He'd never planned on it after all. But he would miss them more than he was willing to admit.

This is why the day when Cas asked Dean to come with him was probably the best day of Dean's life. Dean never gave Cas a spoken answer, but the hug that literally swept Cas off his feet and the deep kiss Dean gave him after the question served as more than enough of a reply.

They all decided to leave together that summer. Sam came over to Cas's house with Dean to say goodbye. He had never been as close with Cas and Jo as Dean was, but he was still going to miss them. And of course he was going to miss Dean more than he could ever say. He gave all three of them warm hugs before they got in their cars. Dean gave him a second hug, along with a, "See you soon, Sammy," before climbing into the driver's seat of his Impala next to Cas. Sam waved at them as they drove off.

As they made their way to Chicago, Cas couldn't keep himself from smiling. He found it hard to believe that he was here, that something like this was happening to him. Dean glanced over and saw the tiny smile. Even though Cas couldn't see it, Dean smiled back and reached over to grab Cas's hand, holding it in between the seats. And although neither of them said anything, they were both in agreement that, in that moment, they were the two luckiest people in the world.
