ahaha. I have a lot of fanfiction. I might give you a few options since I can't really pick right now.

In Club Le Boa, France is a bartender and England is a patron. I'd love to see a subtle sign that they're dating while he's at work, like holding a hand, or fingers brushing while passing over a drink.

Russia and America were ice skating in another story and it was funny. Russia is a skating coach and once tried to go pro. America can't skate to save his life. At first Rus was just leading Ame around while he clung and later he did teach him some and was having Ame skate across the rink toward him.

Otherwise, the end of a cold war based fic with Rus and Ame would do nicely. It would just be them shaking hands but it's such an emotional moment.

If you want to read something, I'll give you the links to whatever interests you.
