我非灯泡却为你发光你非阳光却亮我心房
[wŏ fēi dēng pào què wéi nĭ fā guāng nĭ fēi yáng guāng què liàng wŏ xīn fáng]
'I'm not a light bulb, but I shine for you; you're not the sun, yet you brighten my heart' implies a selfless devotion and affection, showing how both individuals bring out the best in each other despite limitations.
