我姓刘却留不住他薄凉的心
[wŏ xìng liú què liú bù zhù tā bó liáng de xīn]
It translates as 'My surname is Liu, but I can't keep his apathetic heart'. This implies personal sorrow in a love story. Here the individual expresses their inability to change someone else's indifferent attitude toward them despite forming a close link such as the same surname (a possible play on words in Chinese indicating connection).
