Kirk/Spock de-aged fic

Hi all, looking for a brilliant fic where Spock gets de-aged by an alien race, he gets older if he is happy, and Jim is looking after him and has just discovered that kid-Spock has a crush on him. its a really, really long fic and any help would be appreciated. (crossposted to stxistoryfinder)

This sounds like a reverse Howl's Moving Castle. LOL
