In these lyrics, the protagonist is saying that when they close their eyes, the world ends, but when they open their eyes, the world changes. They realize that what is considered "right" is not always the correct answer, and what is considered "wrong" is not always a mistake. They say that it's easy to know what is important: to live freely and sing their heart out. They believe that if they don't believe in themselves, nothing will change and they won't be able to change. They also mention that they need to feel pain and let their tears flow, and that they should speak with their heart and smile tomorrow. They say that everything will go as they wish. The protagonist also talks about hearing a voice of someone crying and realizing that having a heart that thinks of someone as just "someone" is not good. They mention that they should know the purpose of the warmth of their partner's hands. They believe that if they live freely and sing their heart out, tomorrow will be full of smiles. They say that even a small bit of courage can create a future where they share their loneliness and split their worries and frustrations in half. They say that if one person cries, they will be there to comfort them, and if one person stands up, they will take their hand. They wish for a world and a future like that. They believe that if they believe in themselves, everything will change. They should feel pain and let their tears flow, and speak with their heart and smile tomorrow. They say to live freely and sing their heart out, and to shout, sing, struggle, and grasp. They believe that they can create tomorrow and the future with their own hands. They say that everything will go as they wish. The lyrics end by repeating the beginning, saying that when they close their eyes, the world ends, but when they open their eyes, the world changes. They say that speaking out loud makes the world go around, and they question what it means to be a "person" for the first time in their heart.
