This is the year 2436. People have no joy and only know how to work like zombies. Children only know how to study. Suddenly a boy heard the old man singing softly. "Hey, grandpa, what's that sound?" "This is singing." "I know the song, what kind of song it is. The lyrics are so desolate!" "This is a song of lost love! A song of broken love!" "What is love!" "What is love? I don't know. I only read the song from the books handed down from our ancestors." ……… This is a story. Semi-science fiction, also known as "Indelible Traces" ———— Update by chance!
