@crazy_twilight_chick look, you need to find a natural time when you’re alone with him (don’t try to manufacture something). At an appropriate time—which would be about the time you expect to leave for reasons of your own anyway—take his hand, look into his face, and just give him a kiss and a warm, friendly and hopeful smile.
Then turn and leave, and just let him think and decide what he should do.
The next time you see him—you act as if nothing has happened. The ball is squarely in his court. He can talk about the kiss, ask you what you had in mind, complain, or ignore it as well. (And that might hurt your feelings, but you have to swallow that, if so. Him saying nothing at all would be… what he wants to say.)
He might even kiss you.
If the friendship is a good one but that’s all he wants, then nothing will happen. If he flakes out and avoids you or breaks up the friendship because of your well-meant kiss, then it wasn’t much of a friendship to begin with. And if he kisses you… well… get back to us someday, okay?
