The target audience for the film is 11-19 year old females. To understand what this audience wants, the creators asked friends in this age range what kind of film they would want to see. Most said they preferred romantic dramas. Younger sisters aged 12-14 also provided input, saying they liked romantic comedies or adventure films, especially when an unpredictable relationship develops. The creators incorporated these elements, like gradually unfolding a relationship through a scrapbook, into the film opening.
