January 1, 2005. Erai, a 16-year-old who loves painting, accidentally meets Aya, a songwriter who is 10 years older. Through an unusual introduction, the two agreed to exchange works: Er painted a sketch of Aya's face, while Aya sang Er one song of her creation. Feeling pleased, Er questions their chances of seeing each other again. Aya replied that they might only meet on the next January 1. "Why January 1st? Why wait a year?" "Because I live in a distant place." "Oh, huh? How far is it?" "It's very far away. Somewhere unspoiled."
