你眼闪光芒却只望它
[nĭ yăn shăn guāng máng què zhĭ wàng tā]
It means 'Your eyes sparkle, but you only look at it/him/her', a metaphorical expression that depicts someone whose eyes are shining with hope or desire for something or someone, yet their attention is elsewhere, often suggesting unreciprocated love or admiration from the observer's point of view.
