The Halloween Party
The Halloween party acts as a symbol of teen romance. Aidan and Clare's love starts at the Halloween party where they first meet. Aidan takes over the stage at the party and performs a song that intrigues the entire crowd. One thing that comes out during the performance is that Aidan is self-assured and attractive. Clare falls in love with Aidan even before they have an initial introduction. After the performance, Aidan approaches Clare, and she finds it difficult to resist his charm.
Adventure
Stella is a symbol of fun and adventure. Stella does not miss any party where there is entertainment. When Stella convinces Clare to attend a Halloween party, she is unwilling to go, but she convinces her to attend. For the first time, Clare experiences the meaning of adventure. Since the day of Halloween, Clare joins Aidan in all parties he attends.
Aidan’s parents
Aidan's parents act as symbols of the wrong career choice. From the begging, Aidan knows he wants to be a musician, but his parents have a contrary demand forcing him to do a medical course to be a doctor. Aidan's parents are medical doctors, discouraging their son from pursuing what he loves. Clare knows she wants to be a lawyer, but Aidan is confused about whether to follow his parents' commands or go against them.
