一见如故爱上你形同陌路离开我
[yī jiàn rú gù ài shàng nĭ xíng tóng mò lù lí kāi wŏ]
'At first sight we were like old friends, fall in love with you, leave me as if we are strangers' means that despite feeling immediate connection initially, eventually the person chooses separation and this can imply emotional conflict or unreciprocated love.
