为伊拒绝暧昧伊为他人憔悴
[wéi yī jù jué ài mèi yī wéi tā rén qiáo cuì]
It refers to refusing vague romantic interests ('ambiguous affection') due to loving someone (yi, which represents a beloved), yet paradoxically this yi ends up being troubled by others ('being weary of someone else'), expressing a kind of complex and unfulfilled emotions. The feeling behind it can be associated with the themes explored by classical love stories.
