Maybe it is. The song would seem to be about the pleasures of the flesh — "Ripped jeans, skin was showing," and so forth — but upon closer inspection, seems to be about something a bit less material. The reveal comes in that glorious half-bridge, half-chorus at the end. "Before you came into my life / I missed you so bad," Jepsen sings, and it doesn't make a lot of sense at first. Through the rest of the song, the sequence has been clear. She "threw a wish in a well," and then the object of her wish was "in my way," newly appeared before her. She gives him her number and hopes that he'll call, but one thing is clear: "I just met you." So how could she have possibly missed him before he came into her life just now? The only way would be if she's expressing a kind of spiritual yearning put into her heart by a higher power. We find Jesus, after all; Jesus does not find us. We are created by God and then must find Him. Christians sometimes speak of the salvation experience as a process of feeling a great emptiness without knowing what they lack, looking within their own hearts and welcoming Jesus into it, and finally feeling whole. Before Jesus came into their life, they missed him, without even understanding what it is they were missing.
The point here may not be a literal reading of Christian salvation (and, indeed, some proud American Christians might disagree), but Jepsen's yearning seems spiritually directed. "It's hard to look right at you," she sings, as if her romantic interest were the sun, or a monster. She conjures him with a ritual, and says she'd "trade my soul" for the opportunity. She seems less interested in a relationship or even a one-night stand than she does in something like grace, the nameless, immaterial peace that settles on its recipient for no reason or rhyme. "I wasn't looking for this," she protests, but here it is. Salvation arrives suddenly, and it will decide for itself whether you are chosen. Leave your number and it'll get back to you.
