爱的保质期
[ài de băo zhì qī]
Translated directly as 'Love's Shelf Life', it reflects an interesting way to contemplate relationships; implying that all romances will not last forever, but rather each one possesses a certain period when they are in their peak - before time potentially fades them. It may also suggest a practical approach toward romantic engagements or even self-reflection regarding the sustainability of one's affection.
