Fifteen Years of Waiting for Migratory Birds

First day at school thirteen year old Lily drew attention to the cynical handsome pay of Sansana, which became her ray of light. That weird smart girl and beautiful but disorderly guy drove like heaven. They all envied.
All fifteen years, was Sanchuan heartbroken, upset or backed into a corner, Lily was a true friend. And it was for her a true love. And every year she wanted to love him, but the dream remained a dream. For Sansana Lily was just a friend. He was willing to protect her and to comfort him, but love his attitude to her was not in sight.
But fifteen years were not in vain. Sanchuan finally realized that can't live without Lily. But she could no longer love him. And then his broken heart cried out: "In the next life, Lily, I'll love you first".
