When he was thirteen, Ran met some twenty year old on the street who helped patch him up after getting jumped by a bunch of assholes. That night you’d given him some valuable advice, and he had gained a crush. You turned him down— telling him to try again when he was big and strong and maybe he’d have a shot. Of course you laughed off his attempt, finding him more akin to your little brother as he puffed up his cheeks and declared that he’d marry you one day.

Now it’s eight years later, and Ran’s followed your advice to a tee. He’s finally nineteen, and he’s back to make you his.

(This one is a little complex but that’s okay! User is 28, Ran is 21.)
