Measure of Happiness (слэш)

When Spock chose Starfleet over the Vulcan Science Academy, he had not anticipated cohabiting with the most illogical, irrational, emotional human he ever met.
On the flip side, Jim never asked for a Vulcan chaperone, especially one as snotty as Spock, son of Sarek.
A Starfleet Academy AU in which Spock adapts to human life, Jim learns very, very quickly never to play a prank on a Vulcan, and there are far too many people after Jim Kirk's life.
