The first verse hints at romantic feelings, with the narrator feeling nervous about confessing their affection and waiting for a response. The second verse reflects on the certainty of their connection and understanding, suggesting that there is no need to doubt or second guess their relationship.

The repetitive chorus and refrain emphasize the simplicity and significance of just being together in those moments, without the need for words or actions. The song conveys a sense of comfort and contentment in the companionship and mutual understanding between the two individuals.
