The lyrics of Kacy Hill's song "I Couldn't Wait" describe a deep and intense love for someone who seems to be struggling with their emotions and unable to fully accept the love being given to them. The narrator of the song tries to give all their love, but it always seems to be too much for the other person. Despite this, they are willing to wait and to bet on their relationship if the other person would only try. The night feels soft and comforting, but the narrator longs for the morning light to bring clarity to their situation. The song is a plea for the other person to open up and let their love in, and a declaration of the narrator's commitment to the relationship.
