Now is the time, but I'm still afraid to speak. Something strange has been hidden deep inside me, for so long. Something is brewing, a feeling I've never felt before. It scares me that maybe I can't be the person I want to be. But what does it matter to us? What can I say? Are we from different worlds? Because every breath I take is for you. How can I face this life without you? I'm afraid, there's nothing to comfort me. How can I live without you? I'll be unable to sleep, lose consciousness, lose all my senses. Even in the pain, I can't shed a tear. Then it suddenly hits me that maybe we were never the same from the beginning. And that scares me even more. This dream we shared together can never be realized. Therefore, we must be apart. I can no longer be the person you need me to be. If there's a way to avoid hurting each other, I'll find it. I'll be devastated and fight for it, but I can only live with this impossible dream. If I can't be yours, what will I be?
