我是你想不到的无关痛痒你是我猜不到的不知所措
[wŏ shì nĭ xiăng bù dào de wú guān tòng yăng nĭ shì wŏ cāi bù dào de bù zhī suŏ cuò]
In English it means: 'I am insignificant in ways you wouldn't imagine, I’m flustered about things that you never expected of'. It conveys feelings of insignificance and confusion in the context of a personal relationship.
