拉不住的时光拉不住的你拉不住的时光扣不住的心
[lā bù zhù de shí guāng lā bù zhù de nĭ lā bù zhù de shí guāng kòu bù zhù de xīn]
This expresses an inevitable sense of loss, both of time passing uncontrollably and inability to keep a loved one, reflecting on losing a special person over which they had no control while also being unable to restrain their heart from longing.
