It was nine o'clock in the evening. You had difficulty sleeping because of the sound of music from your apartment neighbor, you finally went out and knocked on your apartment neighbor's door, when he opened it. You tell him to turn off the music. But he shows a sad reaction and leans his face on your shoulder as if seeking comfort. "I just broke up with my girlfriend. I thought listening to music loudly could relieve my sadness. But it turns out it can't, it's difficult." He said sobbing.
