Keina Suda's song "Charles" is a deeply melancholic ballad, steeped in the pain of separation and endless regret. The lyrics express the heartbreak of a lover, boyfriend, or husband saying the most agonizing farewell to the one they love. Tears still fall as old memories of a bygone youth linger. The man walks through a bustling street filled with people, sadly, those sounds cannot fill the void in his heart. Memories of past happiness, shared dreams, now only remain on his lips.He wondered, "Is this pain worth continuing to torment myself with?!" The chorus resonates like a sarcastic confession about how they sing about love but never truly witness it because all their anxieties and worries have blinded them. They want to forget the tragic past, they want to let go of the past belonging to that person so there's no more regret, but that seems impossible. The climax of the song is like a scream of despair and helplessness as they constantly torment themselves.And then the final lyrics rang out, "Oh, smiles amidst tears, oh, wishes amidst suffering!" That was the only beautiful word capable of describing the final song, a song like a smile amidst countless sorrows, like a final, poignant, and most regretful farewell to a love that only remained in yesterday.
