Elsewhere – and to the music of Taylor Swift's Red – we see Belly struggling with her feelings for the two brothers, saying: "When I’m with Jere, everything is easier. But everywhere I go, there’s a memory of Conrad."

At the end of the clip, we see Belly in a white dress, taking a deep breath as she narrates: "Life’s too short not to send it with the person you love."
