只是时光它不懂
[zhĭ shì shí guāng tā bù dŏng]
'It's just that time doesn't understand,' which conveys profound sorrow and reflection. Here 'time' symbolizes people around us or changes over time; 'doesn't understand' indicates regret that people cannot understand or empathize with oneself, suggesting there's always a distance between individuals and a misunderstanding between hearts.
