26-Year-old Lu Yuanchi accidentally heard the song he often sang when he first entered college, and his thoughts returned to that distant yesterday. He vaguely saw his young parents, former friends, and kind teachers slowly walking towards him, but only the girl stood in the distance. He seemed to have forgotten her appearance at the age of 19. When the song ended, he did not extend his hand, and she disappeared into the melody.
Intention: Can we not be angry?
