我非薄荷心却凉我非柠檬心却酸
[wŏ fēi bó hé xīn què liáng wŏ fēi níng méng xīn què suān]
Not Mint Yet My Heart Is Cold; Not Lemon Yet My Heart Is Sour illustrates internal emotions like feelings cold inside despite not being indifferent (as represented by mint), or sour-hearted without necessarily having been bitter (as suggested by lemon), indicating an unexpected emotional state.
