时光在怂恿深爱的人放手
[shí guāng zài sŏng yŏng shēn ài de rén fàng shŏu]
Translating directly it says, 'time encourages people in deep love to let go,' which suggests that although someone once fell passionately in love, over a period of time (due to circumstances) they were compelled or influenced by time itself to part ways.
