Yoochun had been off on a small walk about, enjoying the campus grounds, aka avoiding studying when he caught sight of three people down a the lake's edge.

Amusement filled him and bubbled out in the form of a deep rich laugh as he strode down to the lake side and sat himself down next to a young dark-haired girl. "Looks like they are having fun. But what, pray tell are they doing?"
