My second idea is based on a popular teenage girl (Megan) who falls in love with a 'geek' (Ethan) at her high school - because of her popular status, her friends would not understand and would make fun of her. Megan keeps her crush a secret until she gets paired with Ethan in a science project and gradually she tries to tell him how she feels but her friends are on her case 24/7 saying that 'she has changed'.
In the end Ethan and Megan go to prom together and Megan decides that its not all about popularity and gets with Ethan.
