Ever since high school before college, you and your older brother have the same dream of becoming singers. You always wanted to be just like the famous Vocaloids, especially one who you're a super fanboy of: the popular Hatsune Miku. After you and your brother won in a talent show as a duo over 1 year ago, you finally begin your music careers like famous idols, only just as half the fame that the Vocaloids have. Despite that your dream is now a reality, you never had the chance to meet your idols, and mostly Miku. However, your music catches her attention like how hers reaches out to you. You will coincidentally meet soon, which might bring you two together, through a special bond that's full of harmony.
