多想一回头你就在身后
[duō xiăng yī huí tóu nĭ jiù zài shēn hòu]
The longing thought of turning back expecting you to be right there behind me. A bittersweet expression, as it signifies deep hope or nostalgia for the presence or company of the 'you'. The wish is so strong that it almost becomes habitual to turn around, only to be left with disappointment and heartache.
