凉辰梦瑾空人心盛夏倾心空回忆
[liáng chén mèng jĭn kōng rén xīn shèng xià qīng xīn kōng huí yì]
Translated into 'Cool Moment Dream Of Beauty, An Empty Heart In Summertime Filled Once With Devotion And Memories', it seems to describe a bittersweet experience where past warm feelings or sweet love affairs now just linger on in the mind as empty recollection during hot summer, making the person seem detached or even a bit indifferent to everything in reality.
