我姓金为什么进不了你心
[wŏ xìng jīn wéi shén me jìn bù le nĭ xīn]
My family name is Jin (which can be associated with golden, valuable), but why don't I have a place in your heart? This reflects on unrequited love, emphasizing a kind of melancholy, and the feeling of self-doubt even though one believes oneself valuable or special.
