你的眼深似海却不以我为蓝
[nĭ de yăn shēn sì hăi què bù yĭ wŏ wéi lán]
'Your eyes are as deep as the sea but you do not reflect blue because of me.' It poetically compares someone's eyes to the vast depth of the ocean, implying depth of emotion but the last part reflects disappointment or sorrow as if not seen as important.
