只能隐身守候了
[zhĭ néng yĭn shēn shŏu hòu le]
'Can only hide and guard' implies a deep affection for someone without being noticed or directly involved in that person's life. It reflects a feeling of helplessness and silent protection from afar. The netizen might love someone but cannot be openly expressed and so chooses to observe from the distance while wishing this loved one well
