1. There is a copper sparrow bridge in my heart, in which my little Joe is locked. The world shouldn't make me so happy, but here you are. I want to live with you. I can't live without you. My world is so quiet that I can hear my own heartbeat. The blood in the atrium slowly flows back to the ventricle, and so on. Smart people like to guess their minds. They may have guessed other people's hearts, but they also lost themselves. Silly people, who like to give their hearts, may be cheated, but they may not be able to get others'. You thought I was invulnerable, I thought you were invulnerable. You are mine, but you can't be satisfied, but you can't stay, you can't be satisfied. 6. My heart is a city full of you. 7. If what you gave me was also given to others, I would rather not. I am probably too worthless, so I love you so mercilessly. We are all unloved children, and we have learned to be strong by ourselves. 9. We are all unloved children, and one learns to be strong.
