The music video tells a love story between Taylor Swift and a teenage boy through various settings that resemble Romeo and Juliet, including a high school, castle, ballroom, and park. It follows the narrative of forbidden love between two people from different backgrounds. Throughout the video, the costumes, hairstyles, and settings are used to depict different time periods, particularly Pride and Prejudice and 18th century England. The video draws from multiple genres including modern pop conventions as well as Shakespearean and 18th century influences to portray the romantic theme of the song.
