他是wifi我却不是手机
[tā shì wifi wŏ què bù shì shŏu jī]
It literally says 'He is Wi-Fi, I'm not a mobile phone.' An indirect reference expressing admiration or unattainable longing for something out of reach. Suggests an object of attraction that can't return your feelings just like the device connecting to wifi doesn’t belong together if the holder isn’t its type (mobile/compatible).
