Hardships are things that you expect to go through while in a relationship. So why was Natsuki and Yuri going through them even though they're just friends? Or maybe... more than friends? Their relationship may have indefinitely changed during the sequence of events that has happened throughout life. (Also Monika and Sayori are here)

Hatsune Miku is just a normal high school girl. One day, she becomes a VOCALOID, which changes everything. She even makes new friends. The only question remains: Will everything go the way she wanted it to? Or will everything go wrong?
