The very first Hatsune Miku song I ever heard. After hearing her angelic voice for the first time in my life. I couldn't get it out of my head. She was my first anime crush during my middle school days and I'm glad to see that she's been prospering these years. A lot of people thought she wouldn't make it during her debut but I knew there was hope in her songs. I'm glad to be one of her fans from this song forward.
