“ivy,” the tenth track from evermore, tells the story of a married woman falling in love with a person who is not her husband, leading to an affair.

Swift has sung about infidelity in previous songs, including sister album folklore’s “august” and “illicit affairs”—also a track ten.

Alongside “tolerate it” and “no body, no crime," “ivy” is part of the “unhappily ever after” anthology of marriages, which reunites infidelity, pure toleration and even murder.
