Some fans believe that "Cory" could refer to Taylor Swift's ex-boyfriend, Cory Monteith, who passed away in 2013. However, Taylor Swift has never explicitly confirmed this connection, and there is no concrete evidence to support this theory.
It's important to note that Taylor Swift's songs often draw inspiration from her personal experiences and relationships, but the specific identities and details mentioned in her songs can be symbolic, fictionalized, or composites of various experiences and emotions.
Without explicit confirmation from Taylor Swift or her team, it's challenging to definitively identify "Cory" in the song. Ultimately, the interpretation of the song and the meaning behind "Cory" remain open to personal interpretations and speculations.
