我是你的无关痛痒你是我的不知所措
[wŏ shì nĭ de wú guān tòng yăng nĭ shì wŏ de bù zhī suŏ cuò]
I am irrelevant/insignificant to you; you are overwhelming/confusing/flustering to me. This represents unreciprocated love or affection - while they are just passing existence to someone they admire deeply, that someone makes them feel flustered and at a loss.
