She is a girl with cancer, and he is a singer who has faded out of everyone's sight.
Later, the girl died, and the boy fought his way out of the siege step by step.
The songs he wrote for her were playing in the streets and alleys. When he met everyone, he would say, "This is the song I wrote for my wife."
They met in summer and the story ends in winter.
It seems that everything is changing, and it seems that nothing has changed.
