时间总是怂恿深爱的人放手
[shí jiān zŏng shì sŏng yŏng shēn ài de rén fàng shŏu]
This implies that over time (时光, shiguang means 'time' here), circumstances often force two deeply in-love people to separate. It highlights the painful truth of life where true love might end up defeated by the passing time and reality’s limitations.
