Age Is Just A Number

Allyssa is a normal 12-year-old girl amd Nathan is a normal 9-year-old boy. One weekend Allyssa goes to her cousin, Ashton's soccer tournament and she meets Nathan. Immediately Nathan begins to like her, but Allyssa just looks at him like a little kid. After that tournament Allyssa stopped going to Ashton's soccer practices and other soccer things to avoid Nathan, who she thought was creepy.
One day 6 years later - by then both have forgotten about each other - Nathan goes to his sister, Becca's college soccer game. Allyssa and Becca are on the same team. Nathan and Allyssa start talking and this time Allyssa starts to like Nathan.
