浅蓝过往浅蓝情深海记忆深海鱼
[qiăn lán guò wăng qiăn lán qíng shēn hăi jì yì shēn hăi yú]
A poetic description possibly reminiscing about past events ('blue past') tied with affectionate memories as deep and vast as the ocean, metaphorically representing endless, profound emotions hidden within like marine life in the deep sea.
