3 words. What is real? -- I DO NOT OWN VOCALOID

Miku and Rin are best friends, but are bullied by their classmates and their family left them, taking Mikuo and Len who comforted them. Now, they are helping each other for their needs... Meanwhile, Mikuo and Len try to find them as these four turn 16. Can Mikuo and Len find their sisters? Or they will be forever separated? (Miku x Len, Rin x Mikuo)

Miku is always ignored. At home her brother and father don't acknowledge her unless they want something. At school she has learned over the years to try to stay out of the way and blend in with the backround. The only ones who ever paid attention to her are both gone. Filled with her depressing childhood memories...she feels that she will never be happy again. Until one day... I do not own Vocaloid or the Vocaloid characters all I own is this story :)
