Maya Hawke's song "Stay Open" is about keeping one's heart open and ready for love, even in the face of uncertainty and change. The lyrics describe a willingness to do anything for the person they love, while acknowledging that things will inevitably change over time. The narrator apologizes for losing their partner's key, a metaphor for their own lack of emotional security, and promises to keep their heart open despite the challenges ahead. The song explores the ups and downs of love, and the courage it takes to stay vulnerable and open to new possibilities. Ultimately, it's a message about the power of love to transform us and make us better people.
