Before Scott Leadready II (Spot) came to town, she and Leonard were the closest best friends since were both in daycare. Untill 4th grade when she decided to stop hanging out with him because he's a boy.
In the show, she just adores Spot and is completely unaware of Leonard's eternal love for her. Like the rest of the girls, she's hitting on Scott.
In one episode, while they all play a game of truth or dare, Leonard is told to tell them who his favorite Girl in the class is. Leonard lies and says "Younghee" leaving Leslie upset and a wee bit sad in the process. Hinting that she might be starting to fall for him.
In the future, she and Leonard are married in a nice home with Spot, Jolly, and Pretty Boys sons, Spot Jr, Little Jolly, and Maurice and their son, Scott.
