如果夏天的雨不再清凉
[rú guŏ xià tiān de yŭ bù zài qīng liáng]
If the rain of summer were not cool. A rather philosophical thought here. Summer rains are always related to refreshment and purification. By negating its coolness (pleasant part), the holder might feel disappointed or distressed about certain lost things, or missing out the best parts.
