为他掏心掏肺他觉得有腥味
[wéi tā tāo xīn tāo fèi tā jué dé yŏu xīng wèi]
This translates to 'For him, I pour out my heart and lungs but he thinks it smells fishy'. It suggests someone has given another all their love and affection, only for the person receiving this dedication to view it in a negative light or as repugnant.
