Ghosts can't kiss the living. ~2

Kaito x Len. Kaito wakes up in a strange new world after he was updated with a new software. Re-programmed. He meets Len, Rin and others for the first time. And wonders, why was he picked? The others had forgotten about him for quite some time, after miku was created. So Kaito was left, forgotten about. Until recently, where he meets other vocaloid's for First time. So. Why was he updated? Why was this small blonde boy always by his side . . . Why was he blushing? (( Please don't ask for more, it's 2016 and I haven't wrote vocaloid in years))
