他非暖男却亮我心房我非灯泡却为你发光
[tā fēi nuăn nán què liàng wŏ xīn fáng wŏ fēi dēng pào què wéi nĭ fā guāng]
'He is not a gentle man but he enlightens my heart; I am not a light bulb yet I glow for you.' It means the other person does bring joy and hope even though they’re not perfect and that the speaker shines uniquely and willingly without comparison to objects.
