我在追你为什么要逃你为什么还要拿着刀
[wŏ zài zhuī nĭ wéi shén me yào táo nĭ wéi shén me hái yào ná zhe dāo]
The statement 'I am chasing you, why do you run? Why do you even hold a knife?' is likely metaphorical indicating an unreciprocated attraction, and the 'knife' could symbolize defensiveness or harmful intentions.
