时间煮雨留下比离开还要残
[shí jiān zhŭ yŭ liú xià bĭ lí kāi hái yào cán]
Derived from the popular song 'Time Cooks Rain', it roughly translates as 'After time passes by like cooked rainwater, what is left is more painful than departure'. The user might have experienced sorrowful parting and lingering feelings after the separation.
