If I were to fall, You would fall with me. It came with the blind trust you placed within me. I still struggle to understand it. How you can love me so much. I barely know myself. I can't even trust my own body. My own mind. Yet, here you are. The only person I can put complete faith in. Even as I struggle to remember myself. Who am I? Who was I before? I know you can help me find the answer. So, Yuu, Will you come and fall with me? ℳ.
