The song's actually about a girl losing her boyfriend to drugs. He overdoses while he's on a harsh high and she finds him. That's why she says, "I'll keep you locked in my head, until we meet again." and "That last kiss, I'll cherish, until we meet again." And like when she's saying, "If someone said... blah blah blah" it's like, "I never thought you'd be gone." Like, dead. It's a really sad song. Especially if you see the music video.
