This song is bittersweet. Vanessa is embracing her feelings for Usnavi, while recognizing that they don’t have much time together, and recognizing that the neighborhood itself won’t last forever in the face of gentrification. She encourages Usnavi to stay. He doesn’t quite get what she’s trying to say through his skull. Usnavi’s difficulty opening the bottle of champagne serves as a metaphor for his inability to release his true feeling about Vanessa and the neighborhood.
