Jinyu sometimes thinks that the relationship between people is really wonderful.
The two people went from not knowing each other to becoming familiar and close after a period of getting along and having opportunities. In the end, they inevitably drifted apart and lost their books. Then they began to meet new people and complete a new cycle.
People came and went around me, but there was never a vacancy, but there were all kinds of people around me, and no one ever stopped.
This is probably what it means to be born lonely.
