Can we just think about boyfriends Dean and Benny owning a 24h diner together and at some point they find a guy who comes by during the day and asks if anyone has left free coffees and stuff. Then one night Dean finds himself sleeping on the doorstep of the shop opposite, so invites him into the diner and gives him a meal and stuff. And the next day Benny offering the guy a job in their diner which he gladly takes. Both Dean and Benny fall for this mysterious homeless guy that they find out has a very angelic name of Castiel. Castiel gets really good at his job. He's able to chat to weary customers a blend make them feel happier and make the whole diner run smoother and better. Castiel is a little confused by the flirting he's getting from both Dean and Benny but takes it in his stride until one day, months down the line, Benny and Dean ask if he wanted to be... you know... with them... like with with them... Castiel is all smiles then as the pieces fit together, the shameless flirting from both of them and the smiles and touches. He nods eagerly and both Benny and Dean plant a kiss on his cheek.
