你的眼深似海却不为我蓝
[nĭ de yăn shēn sì hăi què bù wéi wŏ lán]
This is poetic, expressing 'Your eyes are deep as the ocean but not blue for me.' It portrays admiration for another's allure yet conveys an unreciprocated sentiment; even though one finds the other deep and engaging, their connection lacks color or warmth for oneself.
