The Geek and the Jock

In middle school, Sam and Lucas were inseperable. They were two peas in a pod, and geeked out over nerdy games. The two weren't the best looking duo, but they had eachother.
However, in the summer before high school, Lucas transformed into a new person. His newfound good looks helped him to quickly climb the social ladder, leaving Sam in the dust.
Freshman and sophomore year were horrible for Sam, with Lucas being no help.
Come junior year, things are starting to be... different for Sam.
