"Thousand Paper Cranes" is a popular song in the 1990s;
He is a boy whom he fell in love with more than ten years ago. Maybe it is not love, but just childish persistence and liking;
More than 10 years of hard pursuit, more than 10 years of infatuated waiting;
When the paper crane flies across time and space with blessings and love in its mouth, are you still the same person you were then?
About first love, about later, about loving and being loved.
