来自星星的你是我触碰不及
[lái zì xīng xīng de nĭ shì wŏ chù pèng bù jí]
The phrase references the Korean drama title “You Who Came From The Stars”. It means the 'person from another planet' (metaphorically, a person out of reach) represents someone that seems untouchable and unreachable in terms of relationship or emotion. This internet name reflects admiration for someone unattainable.
