"Will You Love Me Tomorrow" is about the gap between a promise made at night and the daylight that tests it. Carole King and Gerry Goffin wrote a song that does not ask where love will go. It asks whether it will survive the morning. The lyric moves through the evidence of the present -- tonight you are mine completely, tonight the light of love is in your eyes -- then stops at the question that undoes all of it. The song understands that intimacy does not guarantee permanence. The most honest love songs are not afraid to look at the clause, to state openly what every person who has ever loved has felt: I believe you now, but belief is not the same as knowing.
