Hi-Five's song "That Was Then, This Is Now" is about the narrator recognizing the mistakes he made in the past and promising to make things right in the present. He addresses a girl he's been with, noticing that she's been acting differently and wonders if it's because of something he did. He admits that he used to pretend she wasn't there and didn't care about her, but now he's grown up and wants to work things out with her. The chorus emphasizes the message that the past is in the past, and now it's time to make things better in the present. Overall, the song is about taking responsibility for one's actions and trying to improve in a relationship.
