How Does the Trailer Use Music to Set the Tone?

Music plays a pivotal role in the trailer, with Taylor Swift’s “Daylight” and “Red (Taylor’s Version)” amplifying the emotional stakes. “Daylight” accompanies scenes of Belly and Jeremiah’s happier moments, while “Red” underscores Conrad’s disruptive return, reflecting the push-and-pull of Belly’s heart.
