Analogince, Red String AU
Roman was a people person. He knew people, and he saw the strings that connected them. Quite literally, too; he saw the red strings of fate tying them together - an intangible, impervious manifestation of fate that only Roman could see. He saw his parents with a taut ref string between them; he saw his brother's, fading into the distance; and he saw his own: a tangled, frustrating ball of ethereal yarn.
He thought meeting his fated would solve the problem, but meeting Logan, besides a daring dive into love and romance, only served to highlight the issue. They were connected, Roman had no doubt about that, and he spared no effort to let his boyfriend know his adoration either, but their string was still frustratingly tangled no matter what Roman did. Sometimes, Roman would ailment that Logan couldn't see strings of fate because surely then his nerd's inner perfectionist wouldn't allow him to be so infuriatingly chill about the problem.
And then they met Virgil. Virgil was shy - unlike Roman or Logan - and introverted - much more than Logan. He shied away from the couple at first, and Roman would have left it at that, until… he felt the tug at his finger. Before his astonished eyes, the tangle of a string began ever so slowly unravelling… and he saw a third line extending without, away from where Roman and Logan were sat, and connecting - casually, as if saying 'what took you so long?' - to Virgil's retreating silhouette.
"Woah," Roman breathed, momentarily floored by the realization.
"I agree," Logan retrieved his boyfriend's attention in a snap. Their eyes met and a silent conversation - and mutual agreement - came to pass between them. "He is rather charming, is he not?"
"I should go and-" call him back, Roman meant to say as he moved to get up.
"Sit down." Roman sat. "We'll meet him again. I'm fairly sure he's in some of my lectures, even. Until then," Logan reached across the table to link their hands - the ones connected by the red string, Roman noticed with a small smile, echoed by Logan himself, "we've got all the time in the world."
