The black-and-white video opens with a voice recording of Gomez, 22, talking about being wronged by a man, presumably her on-and-off boyfriend Justin Bieber, 20. Fighting back tears and revealing little details, she says, "When I was on stage and I was thinking of...I felt like I know...I know him, though, and I know his heart and I know what he wouldn't do to hurt me. But I didn't realize that feeling so confident and feeling so great about myself and then [to have] it just be completely shattered by one thing, by something so stupid. But then you make me feel crazy, you make me feel like it's my fault. I was in pain."
"You got me sippin' on somethin' / I can't compare to nothin' / I've ever known / I'm hopin' / That after this fever I'll survive / I know I'm acting a bit crazy / Strung out, a little bit hazy / Hand over heart, I'm prayin' / That I'm gonna make it out alive," Gomez sings. "The bed's gettin' cold and you're not here / The future that we hold is so unclear / But I'm not alive until you call / And now I bet the odds against it all / Save your advice, 'cause I won't hear / You might be right, but I don't care / There's a million reasons why I should give you up / But the heart wants what it wants / The heart wants what it wants."
