你是一首唱不完的情歌你是一句念不完的情话
[nĭ shì yī shŏu chàng bù wán de qíng gē nĭ shì yī jù niàn bù wán de qíng huà]
'You are an unfinished serenade, an endless sweet nothing' reflects the deep love towards someone who's incomparable. This nickname illustrates one's affection that overflows as if there's so much to tell about this love that it seems impossible to finish singing out or whispering the sweet words.
