不配玫瑰只配他不配深吻只配她
[bù pèi méi guī zhĭ pèi tā bù pèi shēn wĕn zhĭ pèi tā]
'Not worthy of roses, but deserving of him; not worthy of a deep kiss, but worthy of her.' This expresses a self-perception of being unworthy of certain affections but fitting well with specific individuals, possibly referring to unmet ideal relationships.
