Orange/ShounenT

Background
Orange is a song composed by the utaite ShounenT. It's his first VOCALOID original work featuring Kagamine Len (though he had made acoustic covers/arrangements before with Len as the vocalist).

It tells a story of Len, who wants to speak his hidden feelings and thoughts to Rin though is unable to do so. Unable to understand himself or Rin, he let time slide pass by him.

Trivia
