Imagine Spock resigning himself to the fact that Jim will never look at him as more than a friend. He contents himself to be Jim's companion in exploring the shops and museums of the new planets they visit. Meanwhile, Jim keeps trying to make Spock look at him romantically, by planning quiet dates for them to go on, like visiting fascinating museums and shopping for antiques because he knows Spock loves items with history. Basically they're both oblivious, wanting what they already have
Imagine Jim finally working up the nerves to hold Spock’s hand in the art gallery and he reaches out and Spock yanks his hand away and tells Jim that “this is not practiced among friends on Vulcan” and Jim looks up at Spock through his eyelashes and tells him “Well then let go mister Spock.”
and Spock doesn’t.
