从开始认识你我不懂到最后说再见我懂了
[cóng kāi shĭ rèn shī nĭ wŏ bù dŏng dào zuì hòu shuō zài jiàn wŏ dŏng le]
'From not understanding when we first met to fully comprehending our final goodbye.' This reflects the emotional growth one experiences from the start of a relationship until its conclusion, highlighting a journey of enlightenment through the process of meeting, relating, and parting with another person.
