我姓魏却未曾去过你心
[wŏ xìng wèi què wèi céng qù guò nĭ xīn]
In this context, the surname 'Wei' (我姓魏) is used as the first-person subject but implies it can never enter or affect 'your heart'. In English, it could imply 'though I exist and interact with you (my surname Wei), you have never opened up to me truly.'
