Regrets in the characters' songs are portrayed as reflections that guide their aspirations, serving a deeper purpose in their development and personal journeys. This interpretation highlights how the characters confront their past mistakes and experiences, transforming regret into a catalyst for self-discovery and growth. Rather than being something merely to dwell upon, these regrets provide insight into their desires, aspirations, and hopes for the future. By embedding their feelings of regret within their music, the characters articulate their struggles and use those reflections to shape who they want to become, ultimately driving the narrative forward and enhancing the emotional depth of the story. This portrayal creates a nuanced understanding of regret as not just a negative experience, but as a motivating force for change and renewal.
