They met when they were young, loved and hated each other, laughed and cried.
Every love letter, every sentence of "I love you" is ultimately an empty sound.
One day, they will all forget the first meeting at the age of sixteen, the togetherness at the age of seventeen, the deep affection at the age of eighteen, the separation at the age of nineteen, the reunion after a long absence at the age of twenty-four, and the separation of yin and yang at the age of twenty-eight.
Youth will grow old, but you are immortal in my heart.
As long as I remember.
