心中有她眼中是他
[xīn zhōng yŏu tā yăn zhōng shì tā]
'She is in my heart, while he is in my eyes.' It illustrates an interesting paradox within the person - there is a love or longing for someone (a girl) in the heart; however, the person that they see or interact with is not this person, highlighting inner conflict or unrequited love.
